; ; ;

A cyclic voltammetry technique was used to study the interactions of pyrite during bioleaching with the bacterium Thiobacillus ferrooxidans. Potential effects of heavy metals (silver and mercury) and varying the pH on the iron oxidizing ability of the bacterium are reported. Redox potential techniques were used to study effect of ferrous sulfate concentration and pH on bacterial growth.
