Bioleaching of Nicopyrite with Adapted Thiobacillus Ferrooxidans
驯化氧化亚铁硫杆菌从镍黄铁矿中浸出镍

Thiobacillus ferrooxidans are used to leach Ni from nicopyrite. It is found that better leaching is resulted when adapted bacteria are used in contrast to unadapted bacteria. Three factors inhibit adapted and unadapted bacteria in slurry: the concentration of Ni2+ and Cu2+, the presence of sulfide, and the shearing stress. The shearing stress seems to be the most important.
