| 摘 要： | 以生物制剂KZSH01作为还原剂与铁锰多金属矿发生氧化还原反应,研究了铁锰矿的细度和还原剂的含量对还原效果的影响,考察了还原过程中温度和物相的变化,探讨了H2SO4用量对Mn和Zn浸出效果的影响.结果表明:生物还原剂KZSH01可使铁锰矿中93.0%MnO2转化为MnO,90.0?2O3转化为Fe3O4;Mn和Zn的浸出率均大于90.0%;Fe的磁选回收率大于85.0%,79.0%Pb和82.5%Ag富集在渣中.

| Abstract: | 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. |
