Oxidation of Fe(II) iron and bioleaching of pyrite and chalcopyrite by Thiobacillus ferrooxidans was adversely affected by isopropylxanthate, a flotation agent, and by LIX 984, a solvent-extraction agent, each at โ‰ค 1 g/l. The reagents/l were adsorbed on the bacterial surface, decreasing the bacteria
