CSIRO goes for gold

CLEAN Mining, a company involved in the development of the Going for Gold process technology that liberates gold without the use of cyanide or mercury, has taken full ownership of the technology.

The company worked with national science agency CSIRO to develop the technology that uses non-toxic reagent thiosulphate.

Clean Mining is negotiating with ICA Mining Services to commission a plant in the Northern Territory to use the technology and with Nu-Fortune Gold for a plant in Western Australia's Goldfields.

The process has already been put to the test in industry trials, with a first gold pour last year.

Clean Mining managing director Jeff McCulloch said the technology was suitable for greenfields mines and locations where cyanide could not be used or was banned.

He said it could also be used in existing mines that wanted to upgrade or expand.

"This technology provides gold miners with an opportunity to proactively evolve their environmental, social and governance standards," McCulloch said.

"This new technology literally delivers a new gold standard for the global gold industry."

CSIRO research program leader Dr Chris Vernon said the technology would help Australian and international gold miners and end users capitalise on demand for sustainable processes and products.

"Cyanide is used in about 75% of global gold production and while the industry works to manage the associated risk there have been recent toxic spills overseas that have caused great concern to communities," he said. 

"Developing an alternative process, which eliminates hazardous chemicals while maximising gold recovery, meets industry and consumer demands for more sustainably-produced gold."
