  • Gold extraction

    The challenge of attaining economic extraction of gold from refractory ores is one of the main challenges in the mining industry today, as less refractory ores become more depleted. It is thus important to properly select an extraction method for refractory ores, based on mineralogy, precious metal grades, gold to sulphur ratios and hazardous impurities (Mark Aylemore, 2008). Refractory ores ...

  • Extracting Gold | HowStuffWorks

    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. The gravellike material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or ...
