Abstract:
As the largest magmatic Cu-Ni(-Co)sulfide deposit in China and the third largest in the world, the reserves of Co in Jinchuan deposit account for more than 30% of the total reserves in China. It is of great significance to study the characteristics of Co-bearing minerals of ores in Jinchuan deposit and their extraordinary enrichment occurrence regularity for the core scientific problem of metallogenic kinetics of key metal elements, which is extraordinary enrichment metallogenic process and its driving mechanism. The metallogenic mechanism and regularity of Co were discussed by studying the formation and mineralization characteristics of Jinchuan deposit. At the same time, the occurrence state of Co was studied on the main controlling factors of element symbiotic-differentiation and co-associated enrichment mineralization. The results show that there are very few independent Co and Co-bearing minerals of ores in Jinchuan deposit, most of which are Co-Ni sulfide minerals and sulfur-arsenic Co-Ni minerals, mainly including cobalt polydymite, Co-bearing nickelglance, nickel cobaltite and Co-Ni gersdorffite. Among them, nickel cobaltite and Co-Ni gersdorffite are often associated with pyrrhotite or pentlandite, especially most of them exist in pentlandite and Ni-Cu microcrystallites, suggesting that their genesis is also related to magmatism. Co is mainly dispersed in sulfide mineral group(about 90.30%), of which 97% is dispersed in pentlandite and Ni-Cu microcrystallites. About 2.85% of them are dispersed in hydroxymagnesium sulfide mineral group, of which 44.46% is distributed in vallerite; 6.51% is dispersed in gangue mineral group, of which about 73% is dispersed in serpentine. The Ni/Co ratio in pentlandite is about 44.00, and that in Ni-Cu microcrystallites is about 2.00. The Ni/Co ratio in magnetite is about 11.00; among the most widely distributed gangue minerals such as serpentine in Jinchuan deposit, the Ni/Co ratio is about 24.00. There is a certain linear relationship between the contents of Co and Ni of ores. Both Co and Ni mainly occur in pentlandite, indicating that there is a close genetic relationship between Co and Ni.
