  • Gold Processing Methods Gold Ore Extraction

    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. This page offers a comparative review of gold recovery

  • 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.
