Abstract

A bioleaching process has been developed to extract manganese from low grade domestic resources not amenable to conventional mineral processing operations. Between the different strains of microrganisms tested, Thiobacillus ferrooxidans has appeared poor over manganese, Aspergillus niger allowed to obtain high recovery, probably due to the metabolic production of citric and oxalic acids, showing a remarkable complexing and reducing action. The growth of microflora has been correlated to the MnO dissolution as confirmed by SEM observation.
