摘　　要：通过胶磷矿单矿物浮选试验,确定了几种阴离子捕收剂各自适宜的p H环境和浓度。对比浮选效果,选择最佳阴离子捕收剂以及最优配比。单矿物试验结果表明:油酸钠、十二烷基硫酸钠及月桂酸在p H为9至11的环境下,具有较好的捕收性能;药剂捕收能力从强到弱的顺序依次为:油酸钠>十二烷基硫酸钠>月桂酸,棕榈酸>十二烷基磺酸钠>癸酸;十二烷基硫酸钠和月桂酸对油酸钠浮选胶磷矿有积极影响,复配之后的捕收剂可在降低油酸钠用量的同时,有效提高胶磷矿回收率。Through single mineral flotation tests of collophane, the appropriate pH and concentration of different anionic collectors were obtained. Comprehensively comparing the flotation results, the most suitable collectors and optimal ratio of them were determined. The flotation results showed that sodium oleate, sodium lauryl sulfate and lauric acid had better collecting performance at pH 9 - 11 ; The collecting ability of these reagents were arranged in following order： sodium oleate 〉 sodium laur- yl sulfate 〉 lauric acid, palmitic acid 〉 sodium dodecyl sulfonate 〉 decanoic acid. Both sodium do- decyl sulfate and lauric acid had positive effects on flotation of cellophane using sodium oleat as the main collector. The mixed collector could reduce dosage of sodium oleate and increase recovery rate.
