Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …

Once full of gold, the carbon travels to a gold desorption column designed to wash the gold out of the carbon. When this process is complete, all that is left is eluate containing hot water, gold solution, cyanide, and caustic soda. The eluate is transported to the gold room and electroplated onto cathodes wrapped in steel wool.

From the time that the ore hoisted from underground and enters the processing plant, it takes up to five days before the process of smelting into gold bars can commence. South Deep's gold plant has the capacity to process around 330,000 tonnes of ore per month and the capability to treat more underground ore than most other plants in the Far ...

The process involves a chemical reaction between cyanide and the minute particles of gold found within ore, forming a solubilized gold-cyanide solution. From this solution, gold is later recovered, often by carbon adsorption.

Some gold is extracted from placer gold, and some from vein gold. Common gold beneficiation methods include gravity separation, flotation, magnetic separation, CIP, and CIL processes. To extracting gold from minerals with the greatest efficiency, the specific process selection needs to be determined according to the nature of the ore.

Keywords: gold processing, refractory gold, ore mineralogy. Introduction. Gold has been an important commodity throughout much of human history, and is thought to be one of the earliest metals mined (Kongolo and Mwema, 1998; Reardon, 2011). Early gold recovery from stream bed sediments involved manual or gravity-based separation methods; beyond ...
