作了用离子交换树脂从一些工业生产的溶液内和金、钼选厂的矿浆中回收巯基浮选捕收剂的试验。金选厂的试验选厂处理的是高硅酸盐的含金矿石,它含有少量毒砂、黄铁矿和黄铜矿。磨矿到-200目达75%后进入浮选。矿浆浓度为固:液=1:4—4.5,pH=5.5—6,黄 An ion exchange resin was used to recover mercapto flotation collectors from some of the industrially produced solutions and pulp from gold and molybdenum plants. The pilot plant in the gold processing plant deals with high-silicate gold-bearing ores containing a small amount of arsenopyrite, pyrite and chalcopyrite. Grinding to -200 mesh up to 75% into the flotation. The pulp concentration is solid: liquid = 1: 4-4.5, pH = 5.5-6, yellow
