摘要:

青海某铜铅锌矿石属于复杂难选多金属硫化矿石,各目的矿物之间及与脉石矿物之间的关系极其复杂,为了更好地综合利用该矿产资源,对该矿石进行了工艺矿物学研究,查明了矿石中铜、铅、锌的矿物种类、分布状态、工艺特征等。结果表明:矿石中铜、铅、锌矿物主要为黄铜矿、方铅矿、闪锌矿,各有价金属矿物共生关系密切;目的矿物嵌布粒度较细,且分布不均匀;在磨矿细度-0.074 mm占75 %的条件下,目的矿物整体解离度较低。工艺矿物学研究结果为该矿石选矿工艺流程选择提供了重要的基础资料。

Abstract:

A copper-lead-zinc polymetallic sulfide ore in Qinghai belongs to a complex and refractory  polymetallic sulfide ore,and the relationship between the various minerals and the gangue minerals is extremely complex.In order to make better comprehensive use of the mineral resources,the research on its process mineralogy is carried out,which provided insights into the mineral types,distribution status and process characteristics of copper,lead and  zinc  in the ore.The results show that the copper,lead and zinc minerals in the ore are mainly chalcopyrite,galena and blende,and each of the valuable metal minerals coexists in a close way;the target minerals are finely embedded and distributed unevenly;when grinding fineness -0.074 mm accounts for 75 %,the target minerals are in low disintegration degree.The research results of process mineralogy provide important basic data for the selection of ore-dressing processes.
