Leaching of metal sulfides with reagents with thiocarbonyl functionalities

摘要

Problem to be solved: to provide a method for recovering metals from metal sulfides.Solution: the metal sulfide is contacted with an acidic sulfate solution containing a ferrous sulfide and a reagent having a thiocarbonyl functional group, and the concentration of the reagent in the acidic sulfate solution is sufficient to increase the extraction rate of the metal ions compared to an acid free acid sulfate solution A noble liquid containing metal ions is formed.No selection
