Gold is generally found in two types of deposits: lode (vein) or placer deposits; the mining technique used to extract the gold depends upon the type of deposit. Once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carboninpulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore. .
