摘　　要：针对某地白钨矿常温粗选作业进行了捕收剂试验研究。试验研究结果表明,应用SD系列捕收剂在常温(矿浆温度高于20℃)下可获得与捕收剂731相当的钨选矿指标,但在低温(矿浆温度低于15℃)条件下,SD系列捕收剂获得的钨浮选指标优于捕收剂731,其工业试验指标为钨精矿含WO33.01%,作业回收率为78.32%。SD捕收剂具有耐低温、对白钨矿捕收能力强的特点,具有一定的推广应用价值。The collector test was carried out on normal temperature rougher flotation stage of a scheelite ore. The tests show that the flotation by SD series collectors can obtain the closed indexes to 731 under normal temperature（ pulp temperature above 20 ℃ ） but better flotation indexes under low temperature condition （ pulp temperature below 15 ℃ ）. In industrial test of scheelite roughing stage,the concentrate contains 3.01% WO3 with recovery rate 78.32%. SD series collectors have good low temperature resistance and strong collecting ability to seheelite, so SD collector has certain application value.
