Biological agent KZSH01 was used as a reductant to deoxidize ferromanganese dioxide ore containing MnO_2, Fe_2O_3, Pb, Zn and Ag. The influence of the ore fineness and the reductant content on the deoxidization process was studied. The variety of temperature and content in deoxidization of the ore and H_2SO_4 dosage on the leaching effects of Mn and Zn were investigated. The results show that 93.0% MnO_2 and 90.0% Fe_2O_3 are deoxidized to MnO and Fe_3O_4, respectively. The leaching rate of Mn and Zn are larger than 90.0%. The magnetic separation recovery rate of Fe is 85.0%, and 79.0% Pb and 82.5% Ag are concentrated in the residue.
