  • 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.

    One of these is the addition of granular activated carbon to the ore slurry during or upon completion of gold solubilization. The dissolved gold is readily adsorbed onto the carbon, thus removing it from solution, and the granular carbon is separated from the now barren ore by running the slurry through a screen.
