Curing agent for full tailing slag filling prepared by lead-zinc tailing production and application of curing agent
The invention discloses a curing agent prepared from lead-zinc tailings and used for full tailing slag filling and application of the curing agent, and belongs to the technical field of mine filling, the curing agent is prepared from, by mass, 40%-50% of superfine slag powder, 20%-30% of cement and 30%-35% of tailing micro powder, the superfine slag powder is water-quenched blast furnace slag generated during steelmaking in an iron and steel plant, and the cement is water-quenched blast furnace slag generated during steelmaking in an iron and steel plant. The method comprises the following steps: grinding and selecting powder, the tailing micro powder is lead-zinc tailing slag subjected to drying and grinding treatment, and an alkaline active exciting agent and a surfactant are added in the grinding process of the lead-zinc tailing slag. The filling curing agent has good industrial prospects and social benefits.
