(Kitco News) - Clean Mining is negotiating with a Nothern Territory services company to test its cyanide-free process technology, the company announced on Thursday.
Clean Mining said it is negotiating with ICA Mining Services to commission the first commercial plant to process gold using this technology, and with Nu-Fortune Gold to commission a plant in the Goldfields of Western Australia.
The technology was developed by Australia's national science agency, CSIRO, and then transferred to Clean Mining Limited.
The company said successful industry trials were conducted and the first gold pour last year.
"Cyanide is used in about 75 per cent of global gold production, and while the industry works to manage the associated risks, there have been recent toxic spills overseas that have caused great concern to communities," said CSIRO Research Program Leader, Dr Chris Vernon.
"Developing an alternative process, which eliminates hazardous chemicals while maximising gold recovery, meets industry and consumer demands for more sustainably-produced gold."
According to a news release, the Clean Mining process "...replaces cyanide with a reagent, known as thiosulphate, creating a relatively cost-effective, non-toxic and safe alternative to conventional cyanide-based gold recovery process."
