Removing the gold bearing rock from the ground is just the first step. To isolate pure gold,panies useplex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel like material then enters rotating drums filled with
Mercury Usage in Gold Mining and Why It Is a Problem
22/07/2019· A mercury gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is 100 pure, but it does eliminate the bulk of the impurities.
