    Cyanide is a cheap but highly toxic reagent that is very effective in leaching gold from low grade minerals and mining wastes. Therefore, cyanidation is the most widely used method for the extraction of gold from mining wastes. Despite its advantages, is considered an.Ceased. This form of mining usually involves the extraction of secondary gold from placer deposits (alluvial, colluvial or elluvial), which can be liberated and treated using gravity methods. In the Guianas, the most popular form of small scale gold mining is referred to as “land dredging”, a combination of hydraulicking and suction dredging.

    The use of mercury in gold mining is causing a global health and environmental crisis. Mercury, a liquid metal, is used in artisanal and small scale gold mining to extract gold from rock and sediment. Unfortunately, mercury is a toxic substance that wreaks havoc on miners’ health, not to mention the health of the planet.Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets.
