cyanide for gold processing

Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's cyanide has been used to recover gold from gold bearing ores And today over 115 years later most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal The company works to transform gold production worldwide in an environmentally responsible manner The innovative cost-effective process replaces cyanide with a safer less hazardous chemical reagent thiosulphate This inorganic compound helps dissolve fine gold out of ores into a solution which can then be recovered through further processing

involving trucks carrying cyanide to gold plants etc ) The cost of recovering and recycling cyanide from tailings will generally be lower than the cost of purchasing new cyanide When this cost benefit is added to the lower cost of tailings detoxification a strong case can frequently be made for cyanide recovery

The resulting liquid is collected at the bottom and the gold is chemically extracted Heap leaching extracts less of the gold than processing the ore in a mill but is much cheaper There are a few alternatives to cyanide for processing low-quality ores but none are employed very widely to date (1) These alternatives are either expensive

The utilisation of cyanide leaching processes in artisanal mining requires the formation of mining cooperatives or associations to the extent that the gold ore processing using cyanide can hardly be done by individuals In combination with technically advised processing centres and the appropriate working with cyanide this would furthermore

The Clean Mining gold recovery process developed by Australia's CSIRO replaces cyanide and mercury with a safer less hazardous chemical reagent This alternative gold recovery solution is non-toxic and dissolves fine gold out of ores into a solution which can then be recovered through further processing
