Rcovery of gold in pyritic oresMine Engineer

Sulfide ores and pyrites in particular have caused and continue to cause difficulty in recovering the gold values from these ores. In most instances visible gold can not be seen under microscopic examination of pyrite gold ores. However if the ore is ground to -200 mesh most times a few specs of gold can be visibly seen under microscopic

Extracting Gold HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold mining companies use a complex 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.
