摘要
根据矿物性质差异 ,对某含碳酸盐萤石矿进行了浮选分离试验。通过大量的试验找出了对本矿石中方解石等碳酸盐具有有效抑制效果的抑制剂 ,从而成功地实现了萤石与方解石的分离。试验结果表明 ,采用浮选工艺可获得优质萤石精矿 ,CaF2 含量大于 98%,CaCO3含量小于 1.0 %,CaF2 回收率在 85 %以上。
According to the difference of mineral property, flotation tests have been done to separate fluorite from carbonate minerals. Through large numbers of test, thedepressant which can depress effectively carbonate mineralscontained in fluorite ore such as calcite, etc, has been found out. By using this depressant, fluorite can be separated successfully from calcite. The test results show that, high grade fluo rite concentrate which contains CaF 2 over 98% and CaCO 3 less than 1.0%, can be acquired by using flotation process, and the recovery of CaF 2 is more than 85%.
