Introduction Pyrite FeS 2 is the most abundant sulfide mineral on earth and is found in most mining environments. Results and Discussion Microbial community and activity The use of a mixture of mesophiles, which had been collected from the acid mine drainage site of the Zijinshan Copper Mine in Fujian Province of China, may accelerate the dissolution of pyrite due to a strong attachment on the surface of pyrite Full size table.
