    Flowsheet Development For Gold Orebodies

    many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced each year is recovered by this technique. the advantages and disadvantages of gravity separation are similar to heap leaching. It is a very simple and low cost process, but gold recovery is usually low

    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.
