Trans. Nonferrous Met. Soc. China 25(2015) 2718-2724 Function of microorganism and reaction pathway for carrollite dissolution during bioleaching Hong-ying YANG, Wei LIU, Guo-bao CHEN, Yuan-yuan LIU... of microorganism and dissolution reaction pathway of carrollite in the bioleaching process were investigated. The results showed that both indirect and contact mechanisms influenced the leaching process......
for Nonferrous Metals摘 要:This study is to assess the effect of magnesiumrich gangue dissolution on the ore containing chalcopyrite and carrollite from Democratic... stable, much less than that when Mg2concentration is below 20 gáL-1. Meanwhile, the extractions of Cu2and Co2from chalcopyrite with carrollite obviously inhibited by Mg2concentration of over20 gáL-1were......
was studied. The results show that, with the presence of activated carbon, the carrollite dissolution rate accelerates and the cobalt recovery rate increases, which attributes to the galvanic interaction between the activated carbon and carrollite. When 1.0 g/L activated carbon and 20 g cobalt ore are added in the Erlenmeyer flasks that are incubated in a rotary shaker at 180 r/min and constant temperature......
