Bacterial leaching of polymetallic ores from Zlaty Chlum locality

Abstract

As for geology, Zlatý Chlum is a highly varied locality with frequent metaquarzit, amphibolite, quartz as well as deposits of sulphide ores. This work deals with the use of Acidithiobacillus ferrooxidans to bioleach polymetallic ores (Cu, al, Zn, and Fe) from this locality. Leaching lasted for 5 weeks in a bioreactor that ensured optimal conditions for bioleaching. The results imply that the experiments were successful, leaching 54% of Fe, 28% of Cu and 47% of Al.
