processes used to extract the mineral in gold

The two gold refining methods most commonly employed to derive pure gold are: theMiller processandthe Wohlwill process. The Miller process usesgaseous chlorineto extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

    Dec 05, 2019· Put therock powderin a mining pan. A mining pan has holes in the bottom of it like a colander. Because gold is heavy, it will sink to the bottom of the mining pan even while it's submerged in water, while the other minerals wash away. Pour alayer of rock powderonto the mining pan so you can extract the gold pieces.

    Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
