摘要/Abstract

摘要： 为了实现磷矿石的低温（10～12 ℃）正浮选，以湖北树崆坪矿区后坪矿段重选尾矿为对象，开展了12种磷酸酯类表面活性剂强化低温浮选试验。结果表明，AEO-3P、APE-4P、EB-10P 可以作为低温浮选增效剂，其中AEO-3P的增效作用优于APE-4P、EB-10P；MAP-K，ODEP-K的增效作用较弱，其他磷酸酯没有增效作用。说明含有醇或酚基团、聚合度较低、碳链适宜的聚氧乙烯醚磷酸酯才有较好的低温增效作用，没有聚氧乙烯醚的磷酸酯或盐类（PBTCA、HEDP-2Na）反而起抑制作用，碳链较短以及聚合度较大的磷酸酯增效作用不明显，可能是此类药剂的亲水性较强所致。

Abstract: In order to realize the low-temperature (10～12 ℃) positive flotation of phosphate ore， low-temperature flotation tests were carried out with twelve kinds of phosphate-ester surfactants for gravity separation tailings in Houping Mining Section of Shukongping Mining Area in Hubei Province. The results showed that AEO-3P，APE-4P，and EB-10P could be served as low-temperature flotation synergists， and the synergistic effect of AEO-3P is better than APE-4P and EB-10P. The synergistic effect of MAP-K and ODEP-K were weak，and the other phosphate-ester had no synergistic effect. It indicated that polyoxyethylene ether phosphate containing alcohol，phenolic group，with low polymerization and suitable carbon chain has good low-temperature synergistic effect. While Phosphate-ester without polyoxyethylene or salt (PBTCA，HEDP-2Na) play an inhibitory effect. The synergistic effect of phosphate-ester with short carbon chain and larger polymerization is not obvious，may be caused by the strong hydrophilic of such agents.
