What is Gold Extraction? (with pictures) - wiseGEEK

Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or chemical means. The ore is typically mined first, though this is not always necessary, and then subjected to an extraction method appropriate for its ...

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 ...
