摘要
本文对青海某地区多金属硫化矿石进行了工艺矿物学研究。利用多种分析检测手段对矿石的化学成分、矿物组成、矿石粒度以及矿石结构等进行了详细研究。青海该地铜矿以黄铜矿、黄铁矿、闪锌矿和磁铁矿为主,部分黄铜矿与黄铁矿、磁铁矿、脉石矿物等为连生体,粒度较细,难以解离。脉石矿物主要有石英和碳酸盐。详细的工艺矿物学研究为青海某地铜矿选矿工艺的选择和开发提供了理论数据。
The multi metal sulfide ore from certain area in Qinghai province was studied on technological mineralogy .The features of process mineralogy of multi metal sulfide ore ,including the chemical composi‐tion ,mineral composition ,particle size of ore and the structure of ore are studied in detail by various means in the paper .The major part of copper ore contains chalcopyrite , sphalerite , pyrite and magnetite . A num‐ber of chalcopyrite are intergrow th with pyrite , magnetite and gangue , granularity of minerals are fine and difficult to dissociate . The gangue minerals are mainlyis quartz and crbonate . The theoretic basis for the choice of mineral processing technique and exploitation of copper ore from Qinghai is provided .
