陕西某难选钼矿工艺矿物学研究

对陕西某难选钼矿石进行了工艺矿物学研究。结果表明，矿石中金属矿物组成较简单，脉石矿物种类繁多；钼是矿石中唯一有回收价值的元素，硫化钼占总钼的90.26%，主要以辉钼矿形式存在；辉钼矿主要以充填裂隙的形式存在，颗粒发育不完整、粒度较小、分布不均、解离难度大、分选困难；采用阶段磨选工艺回收钼矿物，既有利于减少磨矿功耗和药剂消耗，又有利于提高分选指标。

Process Mineralogy Research of a Refractory Molybdenum Mine

Process mineralogy of a refractory molybdenum ore is studied. The results show that the constituent of metallic minerals in the ore are relatively simple，and the gangue minerals are various in kind; Molybdenum ore is the only recoverable value element.  Molybdenum disulfide occupies 90.26% of the total molybdenum，mainly in the form of molybdenite. Molybdenite mainly occurs in the fractures with features of incomplete development of molybdenite particles，smaller particle size，the uneven distribution，difficulty in liberation and concentration. Molybdenum recovery by stage grinding and separation process can not only reduce the consumption of grinding and reagents，but also improve the separation indexes.
