| Abstract: | The silver in the oxidative silver-manganese ore can be concentrated with united technologies of beneficiation and metallurgy, under the condition of strong magnetic field silver and manganese can be separated from other ores by two steps magnetic separation. The manganese in concentrate of magnetic separation was solved in H 2SO 4 solution as iron chippings and shavings was used, the recovery of 95% for Mn was obtained. The silver in the residue was concentrated by flotation,under the suitable conditions the total recovery of 91.7% for Ag was obtained,while silver in the concentrate of flotation was as high as 13088g/t. |
