中文摘要：
研究了乙黄药、乙硫氮和丁胺黑药分别为捕收剂时，脆硫锑铅矿的电化学浮选行为。结果表明，脆硫锑铅矿在3种捕收剂体系中虽然浮选行为不尽相同，但均表现了较好的可浮性。脆硫锑铅矿的浮选行为依赖矿浆电位。矿浆电位调节所用药剂为过硫酸铵（（NH4）2S2O8））和硫代硫酸钠（（Na2S2O4））。考查了脆硫锑铅矿在不同pH值下，其可浮性与矿浆电位之关系，得出了脆硫锑铅矿的可浮电位-pH区间，为大厂矿区复杂硫化矿电位控制分选提供了理论依据。
英文摘要：
The electrochemical flotation behavior of jamesonite was investigated with ethyl xanthate, sodium diethyldithiocarbamate （DDTC） ammonium dibuyldithiophosphate （ADDP） as collector respectively. It was shown that though it had not the same flotation behavior in the three collector systems, jamesonite really exhibited good floatability in them all. The flotation behavior of jamesonite was also dependent on pulp potential and the reagents for adjusting the potential used were ammonium persulfate （（ NH4）2S2O8 ） and sodium dithionite （Na2S2O4）. Investigation was also made into the relationship of the floatability of jamesonite with the pulp potential under different pH values and as a result, the potential-pH range for the flotation of jamesonite was established, providing a theoretical basis for the potential-controlled flotation of Dachang complex sulfide ore.
