gold the process from ore to the final product

The crude gold is melted and then treated with chloride This converts any foreign elements or minerals still in the gold into chloride which will then naturally drift off the gold The result of this process is 99 5 percent pure gold The final step is to cast the gold into electrodes or anodes and place them in The barren carbon product from the elution columns is transferred to the carbon reactivation plant before transfer back to the CIL train and the gold solution transfers to the electrowinning circuit The final product from the eight-unit electrowinning circuit reports to the gold furnace for smelting

Gold mining is the process of mining gold ores from the ground up till the stage where pure gold is extracted (Richiewiki 2010) The gold ores are usually big and have to be crushed to reduce them to a size of about 12mm diameter before pure gold can be extracted from them The ore usually has to pass various crushing stages each

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

process is usually able to recover 85 to 95 percent of the copper in the ore The dried concentrate contains approximately 20 -30 percent copper by mass 30 per cent iron 30 per cent sulphur with the remainder including small amounts of gold silver and unwanted elements such as arsenic and mercury

Mineral Processing Mineral Processing includes recovery operations at a mine site and the associated processing plant The processing operations involve the extraction of metal ores and minerals from the mined rock Mines use mixers in Backfill or Water Treatment operation

Ore washing (stage 2) may be skipped (the red final column below) in which case the centrifuge (stage 3) will also yield Stone Dust in addition to its usual products (which the ore washer would normally have produced) However the tiny ore dusts from stage 2 will be lost in doing so and in some cases other yields will be reduced as well
