摘要
某铂钯矿位于非洲津巴布韦境内,运用MLA等仪器和手段对其进行了系统的工艺矿物学研究。研究结果表明,矿石中的铂钯矿物种类较多,共有17种,它们的嵌布粒度均较细。矿石中的铂钯矿物与硫化物的嵌布关系比较密切,因此可通过浮选富集硫化物的方式进行回收;但是矿石中有23.68%的铂钯矿物以微细粒包裹体形式嵌布于脉石矿物中,不易解离,对铂钯矿物的回收会造成一定的影响。
A systemic study is carried out on a Pt-Pd ore from Republic of Zimbabwe in Africa with instruments such as microscope and MLA.The result shows there are totally 17 kinds of Pt-Pd minerals in the ore,and the grain size of them is fine.Because of the close association of Pt-Pd minerals and sulphide,Pt-Pd can be recovered by sulphide flotation.But there is about 23.68％ Pt-Pd minerals disseminating in gangue as micro-grained inclusion,because this part of Pt-Pd minerals is difficult to be liberated,it would have some negative effect on the concentration of Pt-Pd minerals.
