辉钼矿属易浮矿物,通过浮选得到含钼45%以上的钼精矿,选矿收率一般可到85%左右.在精矿中产出的尾矿含钼0.5%～1%,比原矿品位高8～10倍,弃之可惜,选矿厂一般是返回再选,但精选尾矿多为细泥状,难以浮选富集,甚至对精选造成不良影响.我国钼矿山每年矿山产出钼细泥折合金属钼约500t,相当于一个大中型钼矿山全年的精矿含量.处理这种尾矿原料一般采取选冶流程,以提高选钼总收率.常用的方法有次氯
Molybdenum ore is easy to float minerals, obtained by flotation containing molybdenum 45% molybdenum concentrate, beneficiation yield is generally about 85% of the tailings produced in the concentrate containing molybdenum 0.5% to 1%, than Ore grade 8 to 10 times, abandoned a pity, the concentrator is generally returned to re-election, but the fine tailings mostly fine mud, it is difficult to flotation enrichment, or even adversely affected the selection of China’s Molybdenum Mine annual mine Output of molybdenum fine mud is equivalent to about 500t molybdenum metal, equivalent to a large and medium-sized molybdenum mine annual concentrate content .Treatment of this tailings raw materials generally take the selection and metallurgy process to increase the total molybdenum yield. Commonly used methods are times chlorine
