Gold is a heavy metal in a group known as the transition metals. Gold is also known as a precious metal (as are platinum and silver). Large amounts of gold are still used in the manufacture of coins, medals, jewelry, and art. Gold also has a number of uses in industry, medicine, and other applications.
These are “refractory ores” and require a chemical, not simply physical, process to liberate gold from the surrounding rock. The Albion Process ™, developed at Core’s laboratories in the 1990’s, is one such process and is now in use globally (see a recent report on a gold Albion Process plant here). Other processes for treating ...

basic process for extraction of the platinum metals has remained essentially the same. Rustenburg converter matte contains about 46 per cent of nickel and 28 per cent copper, together with some other base metals and sulphur. The platinum group metals, together with some gold…
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.

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 carbon-in-pulp.

There’s another form of alluvial mining called artisanal mining. In essence, it is basically the same method employed by gold diggers which involves the screening and straining of mud. In the case of artisanal mining, the extraction process takes a longer time as low tech equipment and manual labor is usually involved.
