Processing, smelting and refining gold World Gold Council

Cyanidation. More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the goldbearing solution is separated from the solids.

Extracting Gold HowStuffWorks

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

MerrillCrowe process

The MerrillCrowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores. It is an improvement of the MacArthurForrest process, where an additional vacuum is managed to remove air in the solution (invention of Crowe), and zinc dust is used instead of zinc shavings (improvement of Merrill).

The process technology and equipment design are described in detail for the carboninpulp process. A typical process flowsheet is given with a description of appropriate design criteria. Technical advantages and disadvantages as compared to the traditional countercurrent decantation process are discussed including some illustrative comparisons of capital and operating costs.

In the carboninpulp process activated carbon is mixed with a ground ore plus water slurry in which gold and silver cyanides are dissolved. After the precious metals are adsorbed onto the carbon, the loaded carbon is separated from the pulp and stripped. The barren pulp is disposed of as tailings and the precious metals are recovered from the strip solution by electrowinning or zinc precipitation. The carboninpulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. This is done to produce a feed suitably sized so that subsequent leaching is rapid. The ground ore overflowing the sizing device generally runs at 25 to 35 percent solids. First it is passed through a trash screen to remove tramp oversize, plastics, wood, and other debris. It is then thickened to a requisite 4050 percent solids prior to leaching. This range of pulp density keeps the activated carbon

The most well known carboninpulp plant remains the prototype Homestake plant in Lead, South Dakota. Operating since 1973, this facility treats 2130 tonnes of ore per day averaging 2.7 g gold per tonne. Homestake has also operated small silver carboninpulp plants at Creede and Cripple Creek, Colorado since 1979. Duval Corporation operates a 2720 tonne per day carboninpulp plant at Battle Mountain, Nevada with an average grade of 2.7 g gold and 3.4 g silver per tonne.
