  • Gold Mining and Processing: Everything you Need to Know

    If the gold is located close to the surface, it’s mined with open-pit mining techniques. Gold that’s located farther below the surface is collected with underground mining methods. Large pieces of ore are made into smaller pieces, and then the sand grain-sized pieces are mixed with a cyanide solution to create a watery, mud-like mixture.

  • The Borax Method of Gold Extraction for Small-Scale Miners

    The Amalgamation Methods . Mercury is used in gold mining because of its ability to bind to gold to form an alloy which helps separate the precious metal from rock, sand and other material. The alloy — or amalgam — is then heated, often in a shovel or metal pan over an open fire, to vaporize the mercury, leaving behind only the gold. 1. Amalgamation is carried out in different ways ...

  • Processing, smelting and refining gold World Gold Council

    The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it ...
