DISPOSAL OF TAILINGS OF ORE: THE PROBLEMS AND SOLUTIONS

Evdokimov S. T., Evdokimov V. S.

The results of the study the possibility of utilization of tailings sands formed as a result of industrial activity flotation of lead-zinc concentrator. Recoverable value is sulphides in the tailings (average lead content - 0.21%, zinc - 0.50%, gold - 0.17 g/t) and consumer – nonmetallic part (8085% of quartz (up to 65%, feldspar, chlorite). Dispose of sulfide concentrates  are  trademarks selective in two steps removed from the tails of the sulfide product that is processed by the existing technology of production, together with the ore or yourself. Extraction of the tail sulphides effected using channel hydroseparator. Based on the theoretical analysis of the impact wall on the movement of the solid particles in the set recommended feeds plate packs in order to obtain thin work areas. The heavy fraction hydroseparation revised scheme and direct selective flotation regime Sheridan – Grissvolda in selective concentrates of high performance. A distinctive feature of the circuit construction of flotation is countercurrent flow jet supply source (both flotation ) and rougher concentrate. The conditions of manufacture and formulation of the non-metal parts of the tails of quality products: silica bricks, glass bottles, glass, marblita. The research results prove the possibility of a full old tailings disposal of lead-zinc processing plant that meets the environmental rehabilitation of territories.
