·The gold dissolution rate is much faster than cyanidation under similar test conditions Additionally the passivation f ilm on the gold surface is eliminated in the presence of halides
·HZO does not attack the cyanide at all when the PAL process i; used The additional gold recovered easily pays for the supple mentary reagent and investment costs for the implementation of the PAL process Future plants can be designed much smaller than plants using the conventional cyanidation technique for a given throughput
·Carbon in leach and carbon in pulp are continuous processes that use activated carbon in a cascade of large agitated tanks which have been widely used to recover or concentrate precious metals in
·Commercially sulfite or Caro s acid are commonly employed to treat cyanidation tails from gold plants to achieve regulatory requirements and the International Cyanide Management Institute ICMI Code compliance of less than 50 mg L 1 WAD cyanide for the discharge of cyanidation tails into a tailings storage facility TSF
·As a result of these environmental concerns a few countries and US states have banned the used of gold cyanidation In response the gold mining industry has promoted adherence to a voluntary cyanide management code with strict independent audits of signatory companies Some environmental organizations have applauded the code for
·CYANIDATION OF COPPER CONTAINING GOLD ORES Due to the dwindling resources of simple cyanide extractable gold deposits a large proportion of the gold processed in the 21st century will be recovered from complex gold ores many of which will contain copper minerals It has been estimated that about 20 % of all gold deposits have significant
