Mercury production from sulphide concentrates by cupric ...

The Bureau of Mines developed a hydrometallurgical method for treating mercury sulfide concentrates to recover mercury. Sulfide flotation concentrate from the McDermitt Mine (Nevada) was leached in a cupric chloride solution at 80° C. The cupric chloride concentration of the solution was maintained during leaching by chlorine sparging.
