Trans. Nonferrous Met. Soc. China 31(2021) 2479-2492 A novel technology of high-voltage pulse discharge for comminution of galena ore Yong-hong QIN1,2, Peng GAO1,2, Shuai YUAN1,2, Ning-yu ZHANG1,2... to investigate the comminution characteristics of galena ore. The optimal experiment parameters were determined as follows: spark gap spacing of 25 mm, pulse number of 120, and voltage of 25 kV. The mass......
on surface of pyrite and galena SHEN Yan-bai1, LI Xiao-an2, WEI De-zhou1, ZHU Yi-min1, JIA Chun-yun1, HAN Cong1 (1. School of Resources and Civil Engineering, Northeastern University, Shenyang... and galena was studied under the condition of various factors. The results show that selective adsorption of Nocardia on the surface of pyrite and galen is obvious. The maximum adsorption rate......
