Processing, smelting and refining gold World Gold Council
Gold refining This refers to processes used to processes used to extract and separate the precious metals in mined material, doré, and from recycled products (jewellery and electronics). The main techniques used to remove the final impurities to create high caratage gold are summarised below:Gold processing Mining and concentrating Britannica,Elemental gold (and silver as well) is soluble in mercury, so that, when particles of the metal are brought into contact with a fresh mercury surface, they are wetted and dissolved, forming an alloy called amalgam. This phenomenon is exploited for the recovery and concentration of fine particulate gold or silver.
Gold processing 101 Mining Magazine
