According to the property of a copper gold ore,exploratory experimental study is conducted on its gravity and flotation separation.The results show that the recovery index of gravity separation is not satisfying and not suitable to treat the ore;the bulk flotation process can obtain the mixed concentrates in closed circuit with gold grade 52.21 g/t,copper grade 21.62 %,gold recovery rate 87.70 % and copper recovery rate 88.91 %,showing good separation performance and technical index;the recovery of barite from flotation tailings with gravity or flotation process achieves effective comprehensive recovery of copper,gold and barite.
