摘要
安徽某铜钼矿矿石中易泥化的蛇纹石含量高且含有小鳞片状的滑石,属难选矿。针对该矿矿石性质,试验确定了铜钼等可浮-铜钼分离-铜硫混合浮选-铜硫分离的浮选方案,通过降低浮选矿浆浓度、使用低粘度的起泡剂MIBC和加大水玻璃用量等技术手段有效改善了钼浮选效果。闭路试验获得了良好的分选指标:铜精矿品位为18.31%,回收率为80.39%,钼精矿品位为47.79%,回收率为87.26%,硫精矿品位为39.25%,回收率为68.92%。
The Cu-Mo ores from Anhui province were refractory ores due to its high content of easy-toslime serpentine, and contain talc with small scale. Directed at the ore properties, the floatation scheme of Cu-Mo iso-flotation – Cu-Mo separation – Cu-S bulk flotation – Cu-S separation was determined by means of test, the flotation result of molybdenum could be effectively improve by using techniques such as reducing the flotation slurry concentration, using MIBC with low viscosity as foaming agent, and increasing the dosage of water glass. The excellent separating index was obtained in the closed circuit test as followings: Cu concentrate grade is 18.31% and recovery is 80.39%, Mo concentrate grade is 47.79%and recovery is 87.26%, S concentrate grade is 39.25% and recovery is 68.92%.
