Discovered in 1886, it produced 25 percent of the world's gold by 1899 and 40 percent by 1985. The discovery of the Witwatersrand deposit coincided with the discovery of the cyanidation process, which made it possible to recover gold values that had escaped both gravity concentration and amalgamation.
activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurries. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carboninpulp (CIP) and the carboninleach (CIL) processes, have been widely used since the 1970s. Due to the economic

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 process for removing gold from gold ore is cyanide leaching. The short version of this process: grind the gold ore to a fine powder, then mix it with an aqueous solution of sodium cyanide.
