Research and Application of Key Technologies for Efficient Separation and Comprehensive Recovery of Complex Polymetallic Mines
With the polymetallic ore of Yinman Mining as the test object, in view of the fact that the tin content of this ore is the highest, and the copper and zinc contents have reached the evaluation standard of the co-associated components of tin deposits with large potential value, the technical route of" preferential separation of copper ( silver)-zinc sulfur flotation-tin separation" is put forward, and finally the copper silver concentrate with recoveries of 79.08% and 87.28% for copper and silver, zinc concentrates with recoveries of 50.81% and 4.18% for zinc and silver, sulfur concentrate with a sulfur recovery rate of 51.57%, tin concentrate with a tin recovery rate of 56.07% and a tin grade of 33.09%, tin concentrate with a tin recovery rate of 5.52% and a tin grade of 32.60%, a tin secondary concentrate with a tin recovery rate of 4.92% and a tin grade of 3.28%, as well as the tin secondary concentrate with a tin recovery rate of 5.54% and a tin grade of 3.28% are obtained. All the indexes meet the specified requirements, and the efficient separation effects are obtained.
