Abstract: Cobalt rich sulfide minerals are developed in Baicao mining area of Hongge ore field in Panxi. The research on their genesis and formation environment is relatively weak. In this paper, the mineralogy and mineral chemistry are used for a systematic study. The results show that the main cobalt-rich sulfides in the ore are pyrrhotite, pyrite, pentlandite, and siegenite. The average contents of Co and Ni in pyrrhotite are 0.21% and 0.42% respectively, and the average value of Co/Ni is 1.10; The average contents of Co and Ni in pyrite are 0.18% and 0.29% respectively, and the average value of Co/Ni is 0.77; The average contents of Co and Ni in pentlandite are 2.67% and 34.30% respectively, and the average value of Ni/Fe,S/Fe and M/S# are 1.08,1.91 and 1.13 respectively; The average contents of Co and Ni in siegenite are 24.30% and 22.90% respectively, and the average value of Co/Ni is 1.06. According to the pyrrhotite-pyrite mineral thermometer, the crystallization temperature of the Baicao cobalt rich sulfide is about 267-490℃, which indicates that it was formed at medium high temperature. Compared with the characteristic values of S/Fe and M/S# of the mantle xenolith pentlandite, the pyrrhotite has the characteristics of troilite (Tr) homomorphic polycrystal, which reflects that the ore-forming materials were derived from the mantle. The geochemical characteristics of cobalt in Baicao mining area show that in the process of sulfide melt separation, cobalt migrated to mono-sulfide solid solution to form Po-Py solid solution, and then migrated further to form Pn and Se solid solution, forming the phenomenon that the content of Co in Se, Pn, Po-Py and Ccp decreases gradually.

Key words: cobalt-rich sulfide, cobalt, EPMA, geochemistry, Baicao mining area, Hongge V-Ti magnetite ore field
