Particle size effects in the microbiological leaching of sulfide concentrates by Thiobacillus ferrooxidans
Journal Article

· Biotechnol. Bioeng.; (United States)
A study is presented of the effects of leaching on particle size when Cu and Fe are leached from a chalcopyrite concentrate and Zn is leached from a ZnS concentrate by Thiobacillus ferrooxidans. A shrinking particle model is proposed to describe the leaching behavior. Cumulative mass-based particle size distributions are calculated by a computer program based on the model.
