Gold treatment with sulfuric acid is the process of dissolution of metals such as zinc, iron and other metal impurities using dilute sulfuric acid (H2SO4) and of the acid treatment process will be easier to concentrate on the stage before the phase of purification of the melting process for making pure gold, because. metallic impurities such as zinc, iron and other impurities that are integrated with the content of gold ore has been dissolved by liquid sulfuric acid (H2SO4). The process of Acid Treatment on gold is very important to do before proceeding to the gold metal smelting process, due to deposition of the cementation process is carried out is still a lot of metal-containing zinc, iron and tin are also entrained. In the use of dilute sulfuric acid (H2SO4) is a blend of metal impurities will easily soluble by dilute sulfuric acid (H2SO4), is a metal that has a positive electrode potential in electrochemical series is rather difficult to dissolve, because the greater the tendency to become ions, and vice versa. A metal with a more negative potential shifts the metal underneath any of the salt solution. Sulfuric acid (sulphuric acid) is a highly corrosive strong mineral acid with the molecular formula H2SO4. The historical name of this acid is oil of vitriol. The sulfuric acid is a colorless to slightly yellow liquid which is clear or viscous and is soluble in water at all concentrations. It is a dibasic acid. The corrosiveness of it is mainly due to its strong acidic nature, strong dehydrating property and if concentrated strong oxidizing property.
