; 文献标志码:A Effects of crystal structure on differences of chalcopyrite and pyrite bioleaching MA Jun1, 2, WANG Ju-xiang1, WU Biao1, WEN Jian-kang1, SHANG..., Beijing 100814, China) Abstract: The effects of the crystal structure of chalcopyrite and pyrite on the of leaching rate and bacteria community succession of these two minerals bioleached under......
Investigation on microwave heating for direct leaching of chalcopyrite ores and concentratesKubra Onol,Muhlis Nezihi SaridedeDepartment of Metallurgical and Materials Engineering, Faculty... of microwave heating on the direct leaching of chalcopyrite ores and concentrates were investigated. The results of microwave leaching experiments were compared with those obtained under conventional......
Electrochemical and spectroscopic study of interfacial interactions between chalcopyrite and typical flotation process reagentsGustavo Urbano1,Isabel Lázaro1,Israel Rodríguez1,Roxana Larios3,Roel... a greater hydrophobicity of chalcopyrite are primarily CuX and S0,whereas oxides and hydroxides of Cu and Fe as well as an excess of starch decrease the hydrophobicity.A conditioning of the mineral......
Dissolution characteristics of sericite in chalcopyrite bioleaching and its effect on copper extractionYing-bo Dong,Hao Li,Hai Lin,Yuan ZhangSchool of Energy and Environmental Engineering,University... extraction in a chalcopyrite bioleaching system were examined. Finer particles,appropriate temperature and rotation speed for Acidithiobacillus ferrooxidans resulted in a higher Al3+ dissolution......
