Abstract
The bioleaching of copper ore from the Caraiba Mine was assessed. A microorganism, Acidiothiobacillus ferrooxidans, was isolated from samples collected directly in acid mining drainage in a gold mine tailings pound and used in the bioleaching of the copper sulfide ore. This ore is composed mainly of 28% of oxidized species, 43% of secondary sulfides and 24% of primary sulfide. The shaking flasks experiments with the Caraiba ore showed copper chemical leaching of about 37% and copper bioleaching of about 60% within 60 days at low temperature and native microorganism.
