| Abstract: | 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. |
