    Gold is processed by cyanide milling a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity according to Mineweb. Heap leaching is a less expensive method of gold extraction but it is a longer process and it recovers less gold than the cyanide milling process.

    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.
