copper arsenic flotation selectivity

Oct 01 2017 · The bulk rougher copperarsenic concentrate then is reground in a closed circuit with a cyclone to become the feed to the arsenic rejection stage • The separation flotation stage has two steps The first step is arsenic flotation at −200 mV SHE under nitrogen gas to selectively depress the nonenargite copper minerals and float the enargite
