Heap leaching is a less expensive method of gold extraction but it is a longer process and it recovers less gold than the cyanide milling process Gold mining teams include geologists who analyze rock structure to guide mining explorations engineers who plan extraction and blasting strategies and miners who do the work of removing the ore

A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury leaving behind the gold This process does not result in gold that is 100 pure but it does eliminate the bulk of the impurities

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 grinding process reduces the rock to a slurry The SAG mill is a large revolving cylinder Rock is ground by the turning action of the mill and impact from the hardened steel balls and the rock itself In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen 5 which acts like a large sieve

Removing the gold-bearing rock from the ground is just the first step To isolate pure gold mining companies use a complex extraction process The first step in this process is breaking down large chunks of rock into smaller pieces At a mill large machines known as crushers reduce the ore to

A stamp mill consists of a set of heavy steel iron-shod wood in some cases stamps loosely held vertically in a frame in which the stamps can slide up and down They are lifted by cams on a horizontal rotating shaft As the cam moves from under the stamp the stamp falls onto the ore below crushing the rock and the lifting process is repeated at the next pass of the cam

Jul 03 2015· How the Extraction Process Works Cyanidation is not used to extract large size gold nuggets from ore because the process is deemed too slow and is not cost effective In mining operations that contain larger free-milling type gold deposits stamping and traditional gravity separation methods are more effective
