Jianhua Chen, Auteur ; Ye Chen, Auteur ; Zongwu Wei, Auteur |Laboratory and industrial scale experiments were conducted to investigate the effect of tertiary dodecyl mercaptan (TDM) as a collector on the flotation of auriferous pyrite and arsenopyrite. The optimum recovery of gold associated with aurifero[...]

Jianhua Chen, Auteur ; Ning Yang, Auteur ; Wei Ge, Auteur |This article investigates the two regime transition points for bubble columns with the so-called dual-bubble-size (DBS) model featuring the utilization of a stability condition to analyze the compromise between dominant mechanisms. Our previous [...]

Ye Chen, Auteur ; Jianhua Chen, Auteur ; Jin Guo, Auteur |The electronic structures of bulk sphalerite containing 14 typical kinds of impurities were studied by density-functional theory (DFT). The calculated results show that the presence of Cd, Hg, Ga, Ge, In, Ag, Sn, Pb and Sb could increase the lat[...]
