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。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.
