PROCESS FOR RECOVERING NON-FERROUS METALS FROM THE AURIFEROUS PYRITES RESULTING FROM THE CYANIDATION PROCESS

摘要

The invention relates to a process for the recovery of non-ferrous metals from golden pirides resulting from the cyanuration process by conditioning with activated charcoal for the precious metals with sodium hypochlorite or sulfur dioxide and finally with perhydroles for the destruction of cyanides. in the so-conditioned turbine, the flotation reagents are added: sodium tiosulfate 150 g / t, copper sulphate 100 g / t, mixture of ethyl xanthoate and isobutyl 100 g / t and AGF 250 25 g / t foaming agent and then flotation for 60 min.
