The gold occurring in the alluvium is not refined by any of Nature s processes—but the accompanying minerals or metals are either oxidised or removed hence in the recovery of gold from reefs impurities are often collected and introduced thus making it of lower value than the corresponding alluvial gold and also giving rise to erroneous

The slurry that remains after this process has a very fine particle size Typically 80 of the ore particles are less than 70 microns in size about the same consistency as fine beach sand Such a fine particle size is required for gold liberation the size required for the cyanide to be able to see the gold in the leaching process

Once extracted the gold is refined with one of four main processes floatation amalgamation cyanidation or carbon-in-pulp 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 Mining

Processes based on direct chemical purification and recovery from solution as elemental gold can greatly speed gold processing and virtually eliminate expensive in-process inventories Refining from scrap The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction

A slurry of ground ore water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver This process removes 93 of the gold and 70 of the silver
