| Abstract: |
| According to the ore properties of a low-grade Fe-Mn ore containing silver form Inner Mongolia, a combined process of high intensity magnetic separation-flotation separation was carried out. The recovery rate of TFe reached 81.25%, while the recovery rate of Mn was 82.12% in a Fe-Mn concentrate. The silver was recovered both in Fe-Mn concentrates and silver concentrates, and the total recovery rates of silver were 87.04%. The quality of concentrates met the requirements of subsequent smelting technical. The mineral processing experiment achieved ideal effect of separation. |
