提高铜硫矿石浮选指标的研究

STUDY ON INCREASING THE FLOTATION PERFORMANCE FIGURE OF COPPER-SULPHUR ORE

在石灰调成的高碱矿浆条件下，铜－硫分离困难，采用脱药＋充气搅拌及添加很少量的混合捕收剂－丁基黄药和乙硫氮，可使钢－硫得以有效的分离．浮硫时加少量糊精能显著地提高硫精矿的浮选指标．

While copper-sulphur separation is rather difficult in strong alkaline pulps conditioned by lime,the experiments prove that their separation becomes effective by dereagentization and aeration agitation with the addition of extremely small amount of mixed collectors-butyl xanthate and diethyldithiocarbamate.The flotation performance figure of sulphur concentrate can be raised greatly by adding small amount of dextrine during the flotation of iron sulphides.
