Gold processing: Gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value.
Cyanidation is used for gold that is distributed finely through a mineral matrix. Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the
