    The selective flotation of arsenopyrite from pyrite DeepDyve

    The selective flotation of arsenopyrite from pyrite The recovery and selectivity were optimised by varying the collector and depressant concentration, pH and the effect of copper sulphate addition. It was found that with MAA, depression of arsenopyrite was possible however, the recovery of pyrite was also adversely affected.
