摘要：
The effect of different microbial consortia on the leaching of chalcopyrite was studied at different temperatures and solution compositions with Boliden's Aitik ore in column reactors simulating heap bioleaching. The columns were equipped with sampling chambers and chalcopyrite mineral electrodes in order to investigate the passivation of chalcopyrite. The sampling chambers were filled with agglomerated ore and pieces of chalcopyrite-rich ore. In addition to chemical analysis of the leaching solution and solids the progress of leaching of chalcopyrite was studied by continuous potential measurements with chalcopyrite electrodes. The Occurrence and composition of potentially passivating layers oil the surfaces of the electrodes and the samples taken from sample chambers were examined by optical and scanning electron microscopy.
