| Abstract: |
| According to the magnetic separation of the medium ore (magnetite orebody) from a gold and silver-bearing polymetallic ore dressing plant in yunnan province, in addition to magnetite, it also contains valuable elements such as gold 0.87 g/t, silver 6.69 g/t and so on. In this paper, after grinding the medium ore to -0.043mm and accounting for 90%, the gold and silver were extracted by the low-toxic gold extracting agent "golden cicada", and the magnetite was recovered by the cylinder magnetic separator. Under the best technological conditions, the iron grade of the magnetite concentrate was 62.00% and the recovery rate was 78.18%. The gold recovery was 83.72% and the silver recovery was 63.08% in your liquid, which provided the technical and theoretical basis for the comprehensive utilization of the gold-bearing and silver-bearing magnetite. |
