一种硫氧混合铅锑矿的浮选方法
摘要：
一种硫氧混合铅锑矿的浮选方法，采用碳酸钠作pH调整剂，六偏磷酸钠作微细泥矿物分散剂，硫酸锌与次氯酸钙作脉石矿物抑制剂，硫化钠、碳酸氢铵、硝酸铅作铅锑矿物活化剂，乙硫氮与丁基黄药作铅锑矿物捕收剂，2#油作起泡剂对硫氧混合铅锑矿进行浮选得铅锑混合精矿。采用本发明能够有效回收硫氧混合铅锑矿，在给矿铅品位为0.28％～1.07％、锑品位为0.24％～0.83％条件下，获得铅品位为20.87％～34.55％、锑品位为17.53％～28.40％的铅锑混合精矿，铅回收率为75.21％～82.77％、锑回收率为73.60％～80.75％。
摘要（英）：

The invention relates to a floatation method of sulfur-oxygen mixed lead antimony ore. Sodium carbonate is used as a pH regulator, sodium hexametaphosphate is used as a fine sludge mineral dispersing agent, zinc sulfate and calcium hypochlorite are used as a gangue mineral inhibitor, sodium sulfide, ammonium bicarbonate and lead nitrate are used as a lead antimony ore activator, diethyl dithiocarbamate and butyl xanthate are used as a lead antimony ore collector, and 2# oil is used as a foaming agent, thereby performing floatation on the sulfur-oxygen mixed lead antimony ore to obtain the lead antimony mixed concentrate. The method can effectively recover the sulfur-oxygen mixed lead antimony ore. Under the conditions that the lead grade of the feed ore is 0.28-1.07% and the antimony grade is 0.24-0.83%, the lead antimony mixed concentrate, of which the lead grade is 20.87-34.55% and the antimony grade is 17.53-28.40%, can be obtained. The lead recovery rate is 75.21-82.77%, and the antimony recovery rate is 73.60-80.75%.
