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.

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.

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.
