extracting gold using electricity

  • Uses for Gold Jewelry, Health Care and Technology

    Gold conducts electricity better than all other metals except silver and copper. And it doesn't corrode easily. This makes the metal an ideal choice for plating contacts, terminals, printed circuits and semiconductors. A typical computer, for example, uses gold in both the display and the circuit board.

  • 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. The gravel like material then enters rotating drums filled with

    The process of extracting gold from sulphide ore begins when the trucks deliver the ore from the blast site to the ROM (run of mine) pad at the Fimiston Plant. Here the crusher reduces it to chunks of rock about the size of a fist. The ore is then ground into very fine particles less than one fifth of one millimetre in diameter in large rotating SAG (Semi Autogenous Grinding) and Ball Mills
