Abstract
The authors study potential utilization of oil tailings of a lead-zinc processing plant. Conversion of sulfides into marketable selective concentrates is carried out in two stages: sulfide product is extracted from tailings, first, and processed, second, jointly with current ore material, using the accepted technology, or separately, by jet flotation. Sulfides are extracted from tailings using a channel-type hydroseparator. A feature of flotation scheme is stream counterflow of feed (in both cycles) and rough concentrate. Conditions and composition are developed for manufacturing a quality product from non-metal tailings: lime-sand bricks, glass containers, fiberglass and marbled glass.
