摘要
针对四川某难选低品位磷矿开展试验研究,试验研究表明,采用自主研发的RZ-12正浮选捕收剂、RF-8反浮选捕收剂,在常温条件下,对该矿进行正-反浮选联合工艺选矿,得到磷精矿P2O5品位为30.52%,回收率为70.07%,同时将磷精矿中Mg O含量降低到1%以下,取得了良好的选矿指标。
Experimental research on a Sichuan Low-grade refractory phosphorous ore, experimental studies have shown that,under normal temperature conditions,using direct - indirect flotation process combined beneficiation ore sorting with self--developed RZ-12 direct flotation Collector and RF-8 indirect flotation Collector ,can get PzO5 phosphate concentrate grade 30.52% recovery rate is 70.07%, while reducing phosphate concentrate MgO content to less than 1%. The process makes a good mineral sorting index.
