The classic method of extracting gold is to first dissolve it with a cyanide solution, then replace the gold with the metal from the gold containing solution, or adsorb it by the carbon slurry method, and then recover the gold from the carbon.
increase gangue acid consumption and therefore processing costs. Hence, selective mining is necessary to ensure the delivery of suitable ore to the processing plant, in order to keep the overall operating costs at a minimum.plex control system is in place and is capable of a high degree of selectivity. The paper describes the grade control system in place at Skorpion

The ore is first reduced in size typically 80 passing 75µm to ensure that all non refractory gold is readily accessible for cyanide leaching. There are several variationsminution circuits used in the gold industry, such as: Multi stage crushing and pebble and/or ball milling circuits, typical of older installations.
To isolate pure gold,panies useplex 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 pieces no larger than road gravel. The gravel like material then enters rotating drums filled with steel balls.
