A new technology
\nthat delivers commercial-scale, cyanide-free gold processing has been released
\nby Australian-based company Clean Mining. <\/p>\n
The process replaces
\ncyanide with a safer, less hazardous chemical reagent called thiosulphate. This
\ninorganic compound helps dissolve fine gold out of ores into a solution, which
\ncan then be recovered through further processing. <\/p>\n
The new technology
\nwas developed over more than a decade by Australia\u2019s national science agency,
\nCSIRO, and trialed in Australia in 2018 with Clean Mining\u2019s parent company \u2013
\nEco Minerals Research Limited. This trial proved the thiosulphate solution
\ncould extract gold from ore at an industrial scale. <\/p>\n
Following this Clean
\nMining negotiated exclusive rights to sell and distribute new cyanide-free gold
\nprocessing technology worldwide. <\/p>\n
Clean Mining\u2019s
\nmanaging director Jeff McCulloch said the deal now allows Clean Mining to
\nlaunch the new technology solution and begin its global sales and distribution
\nprogram. <\/p>\n
\u201cThe world has been
\nwaiting for a cost-effective, non-toxic solution to gold processing and Clean
\nMining now offers that solution,\u201d McCulloch said in a statement. <\/p>\n
About 75% of gold
\nextracted from ore is currently processed using cyanide or mercury, which are
\ntoxic to humans and the environment. <\/p>\n
These chemicals are
\noften contained in large storage tanks and, once used, expelled into large
\ntailing dams that can potentially leach into the local surroundings. <\/p>\n
\u201cEliminating cyanide
\nand the associated tailing dams from the gold recovery process is a
\ngame-changer for the sector and, importantly, for the communities where gold
\nminers operate,\u201d Mr McCulloch said. <\/p>\n
Clean Mining will
\ninitially target small to mid-scale miners who can benefit from the
\ncost-effective leaching ore processing solution, which includes a plug-and-play
\nplant that can be customized and scaled to meet individual needs. <\/p>\n","protected":false},"excerpt":{"rendered":"
