  • 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.

  • Arsenic and Antimony Sulphide Minerals in Cyanidation

    The gold in such ores could be free and uncoated and no trouble in dissolving it in clean cyanide solutions would be expected. However some arsenic and antimony sulphide minerals decompose to some extent in alkaline cyanide solutions to form complex reducing compounds which retard or prevent gold dissolution.
