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.
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
Zimbabwe (/ z ɪ m ˈ b ɑː b w eɪ,w i /), officially the Republic of Zimbabwe, formerly Rhodesia, is a landlocked country located in southern Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa, Botswana, Zambia and Mozambique.

Imports of beads have been found at Gokomere and Ziwa sites, possibly in return for gold exported to the coast. A later phase of the Gokomere culture was the Zhizo in southern Zimbabwe. Zhizo communities settled in the ShasheLimpopo area in the tenth century. Their capital there was Schroda (just across the Limpopo River from Zimbabwe).
Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the MerrillCrowe zinc precipitation process and the other is the adsorption of the gold onto activated carbon.
In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process.
These are all extracted during the mining process. Because of the rarity of pgm and its tendency to combine with other metals, the mining process often yields far more nickel or copper than it does platinum. In South Africa, the world''s largest producer, platinum is mined in an area called the Bushveld Igneous Complex.
