J. Cent. South Univ. Technol. (2007)01-0028-04 DOI: 10.1007/s11771-007-0006-3 Influencing factors of pyrite...: The effect of mineral particle size, pulp potential and category of oxidant on pyrite leaching was studied. The results show that a smaller mineral particle size leads to a higher leaching rate of pyrite......

, structure, and function of indigenous consortium during pyrite bioleaching SHEN Li(申丽)1, 2, WANG Jun-jun(王俊俊)1, 2, LIU Hong-wei(刘宏伟)1, 2, YIN Hua-qun(尹华群)1, 2, LIU Xue-duan(刘学端)1, 2, QIU Guan-zhou(邱冠周)1... in modified 9K medium containing 0.5% (W/V) pyrite. The bioleaching efficiency markedly increased. Changes in community structure and gene expression were monitored with real-time PCR and functional gene......
Molecular structures and activity of organic depressants for marmatite, jamesonite and pyrite flotation CHEN Jian-hua(陈建华)1, LI Yu-qiong (李玉琼)2, LONG Qiu-rong(龙秋容)3 1. College of Resources... the depressing performance on marmatite and pyrite. Flotation results show that the organic compounds only with single group of hydroxyl (-OH), carboxyl (-COOH) or amino (-NH2) in molecule are ineffective......
