01/09/2019· 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,pany switched its focus to gold recovery in 2009, and recently rebranded it as the CLEVR process, which stands for chlorine leach vat reactor.
Cyanidation has a history of more than 200 years since it was applied to gold and silver ore extraction in 1887. At present, cyanidation is still one of the main gold extraction process due to its high recovery rate, high adaptability to ore and local production.. Generally, cyanidation methods can be divided into two categories: agitation cyanidation and percolation cyanidation.

Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30 , which is not a worthwhile venture. The use of alkalies such as calcium oxide, will prevent theposition of cyanide in solution to form hydrogen cyanide gas. It reduces the volume of cyanide required to leach the gold or silver. In
