摘要
金宝山铂钯矿属于中国最大的独立铂族金属矿床,铂钯矿石的成分十分复杂,已发现73种矿物,其中有贵金属矿物25种、铂族矿物21种。矿石结构复杂,铂族金属矿物粒度很细,主要为10-80μm,其中20-40μm者占58.18%。贵金属矿物主要分布在蛇纹石中,占46.67%,有25.03%的贵金属矿物分布在黄铜矿中,其他载体矿物有镍硫化物、黄铁矿和磁铁矿等。矿石属于微细粒难选矿石。
The Jinbaoshan platinum-palladium deposit is the largest independent platinum group metals deposit in China. The mineral composition of the ore is very complex. Up to now, 73 kinds of minerals have been found. 25 of them belong to precious metal minerals and 21 are platinum group metal minerals. The ore texture is complex. The granularity of platinum group metal minerals is very fine. It is mainly between 10 urn and 80 um with grains of 20-40 um accounting for 58.18%. The precious metal minerals exist mainly in serpentines and account for 46. 67%. The precious metal minerals existing in chalcopyrite account for 25.03%. Other carrier minerals are nickel sulfides, pyrite, and magnetite etc. The ore belongs to micrograined and fine-grained ore which is hard to be separated.
