Gold Mining In The Carolina Slate Belt


The Carolina Slate Belt is a gold-wealthy strip from Virginia, south through North and south Carolina and ends up in Georgia. Numerous rivers and streams in this area  contain placer gold deposits. Although most people in the US knew of the gold  as a result of the gold rush California, the first gold discovery in the United States in North Carolina was within the Carolina Slate Belt. Gold was first discovered in the United States in 1799 in the Little Meadow Creek in Cabarrus County, North Carolina. 

Although this discovery was not as much attention as the discovery California , In fact most of the experienced gold miners who moved to California, during the California Gold Rush had honed their skills mining areas along the Carolina slate belt. After the first gold find some other discoveries in shale and thus more gold mines were developed. 

Geology In Carolina Slate Belt 

The Carolina Slate Belt majorly composed and derived from rocks that were deposited from volcanic eruption on the surface of the Soil and then sedimentation. The slate is thus characterized by low grade metamorphism that a Large number of rocks is a slaty cleavage here.

Inside Piedmont for the most part consists  and often occur from metamorphic intrusive rocks such as various types of gneiss. The whole region Piedmont is underlain at a depth of Approximately 20 km from a region, the seismic waves reflected emphatically.

This area is often regarded as a series of faults along the upper part, including the uncovered portion of Piedmont, moved westward over a number of completely unknown rocks. The error may twist upward toward the west and rise to the top as one of the various thrusts in the Appalachian Mountains.

The slate is made up of low grade metamorphosed volcanic and slate cleavages. The mountainous Piedmont of North Carolina isolates the Triassic-Jurassic rift basin and the level Coastal Plain from the hilly Blue Ridge and Appalachians. 

The coastal plain consists of Mesozoic-Cenozoic sediments created when the North Atlantic got to be wider and the Triassic-Jurassic rift basins of sedimentary rocks in the plan during the opening of the Atlantic Ocean formed. The Raleigh Belt and Eastern slate belt containing rocks Love that of Piedmont. However, these are only exposed to the east of the Triassic-Jurassic basins and their connection to the Piedmont is not entirely clear.  

The Piedmont can be divided into two parts, the western and eastern areas of both the two very different rock suites. The eastern part is the Carolina Slate Belt, while the western part is often referred to as the interior of Piedmont.  A number of geologists often combine the Carolina Slate Belt and Inner Piedmont, what is commonly known as the Carolina Terrane 

Two of the most important gold mines in the Carolina Slate Belt included :

Haile gold mine
The mine developed from a gold deposit, which was discovered in 1827 on the farm owned by Benjamin Haile in Eastern Lancaster County near Kershaw, South Carolina. The mined operated until the early 20th century operated when the gold deposits originated. This mine was one of the most productive gold mines during the years. 

The Dorn Mine

This is another Large mine in the Carolina Slate Belt. The mine is located in McCormick County, South Carolina. Gold in the mine was first discovered by William soon began Burkhakter Dorn in 1952. The mining at the mine after Dorn and lasted more than 120 years. The slate has several other mines quite a significant amount of gold. In fact, most major gold mines in North and South Carolina Located on the Slate. 

There are numerous other smaller placer mining are found throughout Virginia, North Carolina, South Carolina, and Georgia. All of the gold-bearing areas most rich within these states are found in the slate belt.

Mining has been done in this area for over 200 years, but there are still Nice amounts of gold in the streams and rivers in the Carolina Slate Belt are found.

Source Of Gold Ores


Gold and silver metals are obtained from a variety of different types of rock ores. Most people think of gold nuggets constitute the source of the gold. But the reality is very few gold derived from the nugget. Nearly all newly mined gold comes from ores from natural hard rock mining, fine gold grains, even microscopic particles. 

Gold widely found in nature, although it is one of rare metals. It often happens gold which known as the native metal encased within a mineral such as quartz. And historically gold the most productive, occur in the vein deposits. Currently these widespread deposits give much of the world gold ore

The element gold ores in nature occurs even mainly in the form of native gold, In various gold ores, original gold mineral content commonly occurs, fine mineral particles and small contained within sulfide minerals such as pyrite.

Iron pyrites a very common mineral associated with gold, but it also serves as a reducing agent. Therefore, if gold is found enclosed in pyrite, it is always free gold and not as some kind of gold sulfide. Gold also sometimes in chalcopyrite, galena and arsenopyrite and stibnite, but not as one is found in such quantities as may be found in pyrite. Other minerals such as sphalerite, pyrhotite, magnetite and hematite sometimes carry little amounts of gold as well. 

Gold also comes as Telluride as Calaverit. Common gangue in gold ores include quartz, fluorite, calcite and pyrite, but many others can be found in smaller amounts

Gold Ore Minerals :

The most prominent is pure gold – The most common the native gold contains a Little amount of silver, copper, platinum, etc. 

Telluride minerals are the most common minerals that significant gold in their makeup. These include:
  • Petzite (Ag, Au) 2, Te,
  • Hessit (Ag2Te)
  • sylvanite (Au, Ag) Te2
  • Calaverit (Au, Ag) Te2
  • Krennerit (Ag2Te, Au2Te3)
  • Nagyagit ( Au2, Pbi4, Sb 3, TE7, S7). 
The gold containing sulphides and tellurides, are primary formation from gold ore, although auriferous chalcopyrite could be formed by secondary enrichment process.

Native gold can occur in the primary, secondary enrichment or oxidized zones. The tellurides, which are usually associated with pyrite, are widely used, though not so often, but not always recognized; in fact, some of the miners they are mistaken for sulfides  

Common types of gold ores

Gold deposits are often classified according to their association. 

1. Of these can be cataloged as quartzose.

This means that the gangue mineral is acid, that is, quartz and fluorite which may be very abundant or the other gangue minerals of the alkaline soil group. Not infrequently, it seems varies pyrite and limited amounts of chalcopyrite and galena within quartz quantities. These are free milling ores.

Through a free milling ore it is meant that the rock does not require roasting before the gold can be recovered therefrom. Dry ore is the term that is often used for this category. 

2. Copper ores containing gold ore mineral

These are widely used in the United States and much of the chalcopyrite is gold bearing. This auriferous copper ores are particularly abundant in Colorado, Utah, Montana and British Columbia. They are also in Gold Hill, North Carolina and in Canada to Newfoundland. 

3. The class of gold ore is auriferous lead ores.

The proportion of lead in these rocks is large and the gold content is often low. They are refractory ores such as copper ore. The refractory ore is a meant requires roasting before extraction processing. The heavy sulphides as copper, lead and antimony require this method of treatment, that is the condition of the gold in the mineral will not allow of its immediate capture with most recovery systems.

4. gold ores comprises the gold-telluride group

The gold telluride ores occur accompanied by other tellurides with silver, lead and antimony or as native gold accompanied by other tellurides.  These ores are often sent directly for the treatment of smelters. 

5. Type of disseminated ore.

They are often low in grade, but present in very large numbers. They fill large fracture and fault zones or replace certain geologic horizons. They are the result of the circulation of large amounts of heated water deep underground.

Drill Testing To Sample Gold Deposits


Test process drilling for gold is an important step in the every prospecting and gold mining industry. Test drilling is a step that is used continuously to obtain samples of bedrock in the land of gold mining project. The sample is then tested to determine whether it is gold in the project area in mining and to estimate the amount of gold that can be mined in the area. 

In the process of drilling testing can produce a variety of results sample, because each gap can occur various kinds of different types of rocks and soils, The process of drilling test is a step that most highly effective to get the test results of rock in the ground in estimating the amount of gold ore deposits in the area which will do the mining.

Drilling is an absolute necessity to assess metal ores prior to the process of exploitation in an extensive mining operation. Drilling can be done for all large-scale mining, before the open pit mine development, or for the assessment of large commercial placer mines. 

Preliminary Prospecting Works In Test Drilling

Before test drilling for gold, there are several steps that can be done early, it is made to prospecting works. Often the area to test can bushes, hard terrain or other obstacles drilled, which may influence the outcome of exploratory drilling. It is important, therefore, it will be handled first.

One step that can be used is by ridding the area which will be conducted test drilling. This can help reduce the amount of land the ground which will done testing on drilling,thus support and make to be effective the test holes are drilled. 

Drill testing

In the process of test drilling in gold mining is intended to determine whether the area has gold potential which can be used for large-scale mining.This is very helpful in determining the amount of gold deposits
and grade gold contained in the soil in the area that will be in mine.

Test drilling can also specify the information that is significant of the general geology of the rock structures that exist in the soil at the prospect area, the geochemical structure and other information from other minerals besides gold deposits existing in the test drilling area 

The pattern of test holes, the distance and the number of test wells is mineral determined by the geometrical alignment of the drill, the geochemical composition of the area and the distribution of the target.

For most in scale test drilling in mining area is often gridded out into small grids that can determine the number of holes to be drilled. Sometimes in the drilling process is done in a manner soil formation such as rifts, ditches, river basins or even valleys. 

In most of the tests for the drilling of gold speed and cost are important factors that are considered by geologists.

If in the process the first step is successful, then to get a drilling method that is more accurate in determining the mineral content of gold or may be in the process of the most extensive can be implemented

Some of the methods most commonly used test holes, you can use includes hand drilling, rotary drilling, percussion drilling and diamond drilling. 

The significance of the test drilling for gold

test drilling is to enhance the importance of prospecting before a mining operation, and drill testing is one of the methods most commonly used for sampling.

Albeit with very expensive, it takes some of the risk and guesswork out of the mining process and an estimate of how much gold there is in the area

The type of drilling specifies the device to be used. 

Hand Drilling

This is carried out in at a little place for little operations. Hand drilling done by using a manual hand, the phase required prior training stage, as sample tubes and augers. These drills can not penetrate bedrock and thus limited in its application entirely.

Variety of hand drilling tools can be used for hand drilling, but hand test can only for little gold mining drilling.The advantage of the hard drilling reduced cost of major methods, and this may be the best method for individual miners who lack the resources for greater exploration.

 Percussion Drilling

This type test drilling where the drilling equipment can be used to enter into the bedrock up to a depth of approximately 10 meters. Percussion drilling is drilling that uses compressed air drilling equipment, this makes lebihh far stronger than using a hand drill.There is also drilling using large air drilling equipment ,which can be used in complex drilling in the mining area.

Rotary Drilling

Rotary drilling is drilling relatively expensive yet very easy to use in a variety of conditions. In the drilling process using a ring and an air compressor in the process of drilling holes to be tested. With the true tools and skilled workers, this type of exploratory drilling takes the least time of all available drills. The drill may obtain samples from between 20 and 100 foot holes. 

Diamond Drilling

This is the most versatile drill testing method that can use. The machines used for this type of drilling gets superior most samples since it can drill deep and at a certain angle and conditions.

In most cases, drills are used herein, can be powered by electric engines, gasoline, diesel, and even air. However, the process can only slow and very expensive in practice and thus it is used only for complex projects that require extensive drilling.

Gold In Nevada


Nevada region in the United States is a major industry in the world gold mining, and Gold In Nevada is also one of the world's largest gold resource. Nevada is a part region Southwestern of the United States and the majority of its territory consists of desert semiarid, much of it located within the Great Basin. A number of major mining companies, such as Barrick Gold Corporation , Newmont Mining, Goldcorp, operate gold mines in Nevada.

Gold Prospecting In Nevada was discovered in the 1870s at the vicinity of Carlin in Eureka County with production small, and in 1907 Placer deposits were discovered and the number is still small.  Nevada is well known for its hard rock gold mine production. However, Nevada ranks 6th among the 50 states in placer gold production, with historic gold production of roughly 1.7 million ounces.

Gold In Connecticut United States


Connecticut has a very rich history as a mining state, and Gold In Connecticut has a small amount of prospecting placer gold like many other New England states. Connecticut is the southernmost state in the region of the United States, bordered on the south by Long Island Sound, on the west by New York, on the north by Massachusetts, and on the east by Rhode Island

Just about any river or stream in the state of Connecticut does have some gold bearing gravel and refined gold from Alluvial placers,  those formed in river or stream sediments, because gold is heavier than any of the other materials that are found in the stream it will migrate down through the gravel to either a layer of clay or bedrock. Typical locations for alluvial gold placer deposits are on the inside bends of rivers and creeks so it is rather rare to find much Gold in the middle of the stream.

Gold In Alabama


State in the Alabama has produced a large amount of gold, after the discovery of gold in Georgia, the prospectors began to develop a search in the area of Alabama, and at the end of the 1830s Gold In Alabama was first discovered in the region Chilton County.  The first mining occurred at Blue and Chestnut Creeks.

From 1830 until about 1990 Alabama has produced almost 80,000 ounces of gold, And gold in Alabama has been found throughout Talladega, Tallapoosa, Chambers, Coosa, Clay, Chilton, Elmore, Cleburne, and Randolph Counties.

Find Gold Prospecting In Beach ( Videos )


Gold prospecting in beach is an accumulation of valuable minerals formed by gravity separation during sedimentary processes and in geology called placer deposits . Beach placers form on seashores where wave action and shore currents shift materials, the lighter more rapidly than the heavier, thus concentrating gold .

Placer environments typically contain black sand, a conspicuous shiny black mixture of iron oxides, mostly magnetite with variable amounts of ilmenite and hematite. Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite.

Among the examples of beach placers are the gold deposits of Nome, Alaska; the zircon sands of Brazil and Australia; the black sands (magnetite) of Oregon and California; and the diamond-bearing marine gravels of Namaqualand, South Africa.

Panning Of Gold In Deposit Placer With Gold Panning Equipment

      Gold panning, or simply panning, is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its cheap cost and the relatively simple and easy process.

panning, in mining, simple method of separating particles of greater specific gravity (especially gold) from soil or gravels by washing in a pan with water. Panning is one of the principal techniques of the individual prospector for recovering gold and diamonds in placer (alluvial) deposits.

The typical pan is a light but rugged circular metal dish with a flat bottom and sides that slope out at about 45°. Its inner surface must be smooth and free from grease and rust. In panning for gold from streams, the pan is first filled halfway or so with gravel, soil, and rocks from places where the current is slower (such as downstream of boulders or on the inner side of bends in the stream). The pan is then immersed in the water, and the mixture is thoroughly wetted and stirred. Lumps of clay are broken up, and large stones are picked out. The pan, still under water, is then given a combination shaking and gyratory motion. This allows the heavy particles to settle and brings the lighter material to the surface. At intervals the pan is tilted, and the light surface material is washed off. This process is continued until only heavy “black sands” (such as ilmenite, magnetite, and pyrite) and gold remain. The material is dried and the gold removed (perhaps after using a magnet to remove some of the black sand). Panning is slow, backbreaking work, but in experienced hands there is little or no loss of gold.

How to Finding Gold Prospecting

    How to finding gold prospecting. Gold is found throughout the earth and sea but there are natural spots where we can recover much higher concentrations of this yellow metal. Gold is typically found associated with quartz veins which are located in rock and granite in our planet Earth. While you can find tiny amounts of natural gold in all places, finding concentrated gold deposits takes a tiny knowledge

        Gold is very heavy. Actually, gold is about 19 times as heavy as water - about thrice as heavy as iron. Knowing this makes finding it much simpler. Because of its weight, gold will always sink to the lowest level as feasible. As rain, wind, freezing & thawing, & geologic disruptions move the earth around, gold is freed up & relocates to the lowest point. find gold also depending on the surrounding of the elements of rock (age and type) an outcropping of gold bearing material would appear like a "stained rust mound"

What you would see possibly around the gold would be oxides or sulfides which can contain iron pyrite.  This iron pyrite is also known as "Fools Gold".  The oxides can also contain magnetite and/or hematite, more commonly referred to as black sand. When you pan for gold one of the most common things, besides gold, that you will find will be black sand.

But most gold has eroded and is found in crevices and depressions in rock. The surrounding rock wears away and exposes the quartz vein. Quartz is very hard and will shear away because of its brittleness. Historically, the highest concentrations of gold have been found in primary and secondary deposits. Primary deposits are known as lode ore where gold is originally deposited. In lode ore, gold is found in veins, nuggets and bits. This is embedded in lodes or veins in rock, often together with quartz, silver, copper, platinum and iron pyrite (fool’s gold).

Gold can also be found in the form of free flakes, grains or larger nuggets that have been eroded from the primary deposits and end up in alluvial deposits called placer deposits. Over the years water erodes the exposed lode outcrops and that gold ends up in streams, rivers small creeks, and river beds where it collects. Gold is heavier than most minerals and so it flows with fast moving water and tends to sink and be found in areas where the current slows and is no longer powerful enough to carry the gold.

Gold Panning Machine Speed Up Your Gold Processing Work

Kit includes: Mountain Goat Trommel, Desert Fox Automatic Gold Panning Machine (w/ speed control), and Trommel Transefer Kit. Speed up your gold processing work and increase gold recovery with the Mountain Goat Gold Trommel. This machine is aptly named because it can eat almost anything and is light enough to carry up a mountain! The Mountain Goat Trommel is a reverse helix system built on the same principle as the huge mining trommels used by large mining companies all over the world, but this is light and portable. It is not to be confused with gravel pit trommels, though, which are designed to classify gravels. 
The reverse helix system came from the Archimedes Screw Pump invented over 2,000 years ago by the mathematician Archimedes. Someone discovered that the pump brought up GOLD along with the water they were pumping out of the Nile river! The Mountain Goat is very efficient because the spiral riffles inside of the tube turn and bring the heavy materials up to the high end of the tube while allowing the lighter materials to flow out of the back of the tube as tailings. This system makes the trommel self-cleaning, which eliminates the need to break down for clean-up as is necessary with sluice box type equipment. Recover 50 times MORE GOLD with the Desert Fox Automatic Gold Panning Machine! With the Desert Fox, you can work concentrates down much faster. Not only will your speed increase, your gold recovery and efficiency will improve by a factor of 50. That's not a misprint! You will recover 50 times more gold with the Desert Fox than working by hand with a gold pan. More gold, less time, and a lot less work. And with the new proprietary variable speed model, you can adjust for maximum gold recovery no matter what type of material you are panning.

Gold Panning For Identify Minerals Gold Alluvial


           There may be some of the less know how panning eluvial gold ore found on the path of the river or the prospect area which contains metallic gold ore, and how to identify alluvial gold in river to obtain a suitable sample of gold ore. The place to look for gold eluvial including creeks and ditches along the sides of hills and in depressions between the hills. Alluvial deposits occur on the hillsides and in the hollows between the hills. Then we tried along the river, which at the start of a bend in the curve of the river downstream side or bend in the river because it is usually gold ore are often stuck in there. And we can try to take a few handfuls of sand sediment and then washed with a platter.

           By using equipment made ​​from plastic pots or metal we can do an analysis of eluvial gold ore. And we also need to separate magnetic metal with a gold metal content of iron ore. Before you use these pans equipment wash with soap to remove any residual oil from the sometimes still tied at the bottom of the pan.

Step in gold panning:
Look for areas in the bend of the river that have a prospect of the gold mineral ore. Then fill the pot you use for gold panning with sand, soil and gravel that you think have gold content of ore minerals. 

Placer Gold Mining

Placer deposit or placer is an accumulation of the precious minerals formed by the separation of gravity during the sedimentation process that naturally separate due to gravity and assisted the movement of a liquid medium, solid and gas / air. And placer mining is a very important source of potential resources of gold mining. Geologists frequently mention that the placer deposits Alochton. Density concentrations of heavy minerals is dependent on the level of freedom from the source, specific gravity, chemical resistance to weathering duration and mechanism. These types of deposits have been formed in all geologic time, but most of the Tertiary and the present age, is largely the reserve is small and often clustered in a short time because of an erosion. Most of these deposits have low levels of mineral ores but can be mined because of particle-free, easy to work with without destruction; where separation can use a semi-mobile and relatively inexpensive. Mining usually by dredging, which is the cheapest method of mining.

Some Placer Deposits On The Basis Of Ganesa

Location Of Gold Deposits Eluvial Placers

 Eluvial ore deposits are those such as tungsten and gold placer deposits formed by settling and enriched by the winnowing or removal of lower density materials. Eluvial gold placed by the process of gravity on the surface of the hill, up and flat-lying areas. Particles of minerals or ore-forming mineral deposit type is deposited on top of a rocky hillside source. In some areas found in eluvial placer with ingredients that create economic value accumulated in the pockets of bedrock surface. Rainfall helps to bring the material surface, or floating, downslope. Eluvial deposits consist of fragments of rock and soil which are not consolidated lying on the surface. It is derived from coral quartz and other minerals deposits (supergene, reef quartz and layer) located at the top. Transported material contain gold deposits also form on the surface of the slope of the hill where the concentrated on changes in gradients, like, bottom of the hill. Deposits are usually located near the eluvial placer, which is an irregular surface on the hillside below the mineral resource. 

How To Find Alluvial Gold Deposits

Eluvial placers usually represent a transitional stage between a residual placer and a stream placer. Genesis  or eluvial gold placer deposits formed by precipitation  and reconcentration  gold-bearing sediments from the occurrence of primary gold. Where one type merges into another, they cannot be clearly distinguished. They are characteristically found in the form of irregular sheets of surface detritus and soil mantling a hillside below a vein or other source of valuable mineral. It should be noted that the parent vein or lode mayor may not outcrop at the actual ground surface.Placer deposits are generally  classified  according  to their depositional  environment. Eluvial placers differ from residual placers in that surface creep slowly moves the gold and weathered detritus down hill, allowing the lighter portions to be removed by rain wash and wind. As the detrital mass gravitates downhill, a rough stratification or concentration of values may develop but this is rarely perfected to the degree found in stream placers.Marine placers occur offshore near the coast; fluvial placers occur in river valleys  and in the watershed  are analyzed that contain the incidence  of primary  gold upstream. In conducting searches eluvial gold vein that we need to do  is find a location mountainous areas  or hilly areas that have a strong granite or crystalline deposits is the good end. Area where geological upheaval has occurred and the pressure  is a prime location. The place to look for gold eluvial including creeks and ditches along the sides of hills and in depressions between the hills. Eluvial deposits occur on the hillsides  and in the hollows between the hills.Eluvial placers are typically limited in extent but there have been cases such as at Round Mountain, Nevada, (Vanderhurg, 1936, pp. 133·145) where this type of placer supported large-scale mining operations.
      Eluvial gold can be found in the low hills, rises and flat-lying areas adjacent to the location above. This is often covered with debris of quartz and iron ore. Eluvial deposits are concentrated in the gradient changes, such as the bottom of the hill.supergene deposits found on low hills or flat-lying areas which have developed laterite profile above bedrock. Supergene gold occurrence is difficult to predict because it is controlled by a complex combination of processes
