遵照毛主席关于“综合利用很重要,要注意”的伟大教导,几年来,我们开展了回收萤石的试验研究工作。所研究并准备回收的矿石是一复杂多金属硫化矿选除铜硫后之尾矿。试料在入选前磨矿细度为200目占80％。采用小苏打调整矿浆pH为9～10,矿浆温度从调浆起至浮选终止全过程都保持65℃,浓
In accordance with Chairman Mao’s great teaching on “comprehensive utilization is very important, we must pay attention to”. Over the past few years, we have carried out experimental research on the recovery of fluorite. The ore studied and prepared for recovery is a tailings tailor-made for removal of copper and sulfur from a complex polymetallic sulphide ore. The sample before grinding grinding fineness of 200 accounts for 80%. The use of sodium bicarbonate to adjust the pH of the pulp 9 to 10, the slurry temperature from the slurrying until the flotation termination of the entire process are maintained at 65 ℃, concentrated
