Based in Montreal DST has been working on its chlorination process since the early 2000s. Originally developed to recover nickel from tailings when the price of nickel was considerably higher the company switched its focus to gold recovery in 2009 and recently rebranded it as the CLEVR process which stands for chlorine leach vat reactor
These ponds average one acre. In vat leaching cyanide is mixed with crushed ore in large enclosed vats where gold bonds to added carbon. After removing the gold the spent ore tailings and cyanide are sluiced to a mill tailings pond. These open ponds of cyanide laced debris may cover 200 acres and remain as long as the mine is active
