J. Cent. South Univ. (2012) 19: 238-243 DOI: 10.1007/s11771-012-0997-2 Flotation performances of polymorphic pyrrhotite HE Ming-fei(何名飞), QIN Wen-qing(覃文庆), LI Wei-zhong(黎维中), JIAO Fen(焦芬) School... of different crystalline structures of pyrrhotite (monoclinic and hexagonal) was studied. It is shown that the floatability of monoclinic and hexagonal has obvious difference, and that the flotation recovery......
Flotation separation of marmatite from pyrrhotite using DMPS as depressant SUN Wei(孙 伟), LIU Run-qing(刘润清), CAO Xue-feng(曹学锋), HU Yue-hua(胡岳华) School of Minerals Processing and Bioengineering...; Abstract: Mercapto organic compound DMPS was used as the depressant for separation of copper activated marmatite from pyrrhotite in the presence......

modified with pyrrhotite CHEN Song(陈 松), QIU Guan-zhou(邱冠周), QIN Wen-qing(覃文庆), LAN Zhuo-yue(蓝卓越) (School of Resource Processing and Bioengineering, Central South University, Changsha 410083, China... medium modified with pyrrhotite was studied. Bioleaching of flotation concentrate of sphalerite by the selected bacteria was carried out. The results show that the microorganisms cultured by pyrrhotite......
. College of Resources and Metallurgy, Guangxi University, Nanning 530004, China)Abstract:Electronic structures of monoclinic and hexagonal pyrrhotite were studied using density functional theory method, together with their flotation behavior. The main contribution of monoclinic pyrrhotite is mainly from Fe 3d, while that of hexagonal pyrrhotite is from Fe 3d, Fe 3p and S 3s. The hexagonal......
Bioleaching of pyrrhotite by Sulfobacillus thermosulfidooxidansNI Zhang-yuan(倪章元), GU Guo-hua(顾帼华), YANG Hui-sha(杨慧沙), QIU Guan-zhou(邱冠周) (School of Minerals Processing and Bioengineering, Central South University, Changsha 410083, China)Abstract:The bioleaching of pyrrhotite was investigated using Sulfobacillus thermosulfidooxidans. The effects of pH, pulp concentration, inoculation amount......
