WebSep 17, 2024 · The leaching kinetics of the pyrite, chalcocite and covellite under the studied conditions was successfully modeled by an empirical diffusion-like equation, respectively. The apparent activity energy of pyrite leaching, chalcocite leaching (stage II) and covellite leaching was calculated to be 69.29, 65.02 and 84.97 kJ/mol, respectively.

WebBioleaching of chalcopyrite is always a challenge and research hotspot. The low copper extraction and dissolution kinetics restricted the industrial application of chalcopyrite bioleaching. To solve this problem, the dissolution process and passivation mechanism of chalcopyrite in bioleaching should be first studied, then the rate-limiting steps ... WebAug 31, 2013 · Bacteria: breeding of efficient bioleaching bacteria is the eternal task of biohydrometallurgy. For chalcopyrite heap bioleaching, not only efficient extremely thermophiles are needed, but also efficient mesophiles and moderately thermophiles are needed in order to enhance the oxidation of sulfide ores and shorten the time of heating … crystal cimaglia bombshells
