sulphide flotation - an overview | sciencedirect topics

sulphide flotation - an overview | sciencedirect topics

The favored thiosulfate leaching conditions were 5 mmol/L copper sulfate and 50 mmol/L ammonium thiosulfate at a pH value of 8.5, which allowed less generation of polythionates and their subsequent loading on the resin (0.1 kg/t). Gold and copper loadings onto the strong-base resin were ∼2.5 bkg/t Au and ∼2 kg/t Cu. Copper was eluted from the resin using 0.5 mol/L …
