针对某磷矿浮选尾矿的资源特点,将其作为高镁低品位磷矿进行处理,用萃取-反萃法分离酸浸液中的镁和磷.选择正丁醇作为萃取剂,在磷酸浓度为30%、萃取相比为1:1,温度为常温,萃取时间为5min的均衡搅拌条件下,五氧化二磷萃取率可达68%以上;用水作为反萃剂,在其加入量为反萃前有机相体积的30%,反萃时间为3min,常温条件下进行反萃,反萃率可达90%以上.该研究为综合回收磷矿浮选尾矿提供了基础性资料.

To reclaim resources from phosphate floatation tailings dumped by a big phosphate mine, a lab-scale experiment was conducted with n-butanol as an extraction agent, focusing on the recovery of magnesium and phosphorus. Result shows that more than 68% of P_2O_5. extraction yield can be obtained under the optimum condition, and stripping efficiency reaches up to 90% when using water as stripping agent. As a result, the experiment assists in realizing the integrated recovery of phosphate floatation tailings.
