| Abstract: |
| Through the analysis of the properties of a tin-copper polymetallic ore from Yunnan, the ore deserves refractory ore since the grade of tin and copper is low, the content of sulphur, iron, arsenic, etc is high. Copper concentrate of 14.59% Cu with a recovcry of 79.33%, sulphur concentrate of 30.23% S with a recovcry of 79.33% and rough tin concentrate of 5.759% Sn with a recovery of 68.55% is obtained by using the combined processes of flotation-gravity concentration with stage grinding and stage separation, which makes the comprehensive utilization of mineral resources come true. |
