J. Cent. South Univ. Technol. (2010) 17: 1190-1195 DOI: 10.1007/s11771-010-0617-y Mechanisms of composite agglomeration of fluoric iron concentrate JIANG Tao(姜涛), HU You-ming(胡友明), LI Qian(李骞... of the sinter are greatly improved when using CAP assisted with heat airflow and enhancing magnesium oxide (MgO) contents. For conventional sintering of fluoric iron concentrate, due to lower......
leaching of gold from refractory gold concentrate was investigated. Mineralogical studies on the concentrate showed that very fine gold grains(<10 μm) were encapsulated in pyrite and arsenopyrite..., and As contents were reduced to approximately 19.8 wt%, 6.97 wt%, and 0.13 wt%, respectively. Ammoniacal thiosulfate was used for gold extraction from the biooxidation residue of the refractory gold concentrate......
