Curing agent for non-ferrous metal mine full tailing slag filling and application thereof
The invention discloses a curing agent for non-ferrous metal mine full-tailing slag filling and application thereof, and belongs to the technical field of filling curing agents, the curing agent comprises the following raw materials by mass: 35%-45% of superfine slag powder, 20%-30% of cement, 2%-8% of gypsum and quick lime, and 25%-35% of tailing micropowder, the superfine slag powder is water-quenched blast furnace slag of iron plants, and the cement is water-quenched blast furnace slag of iron plants. Through drying, grinding and powder separation treatment, the tailing micro powder is prepared by mixing non-ferrous metal mineral separation full tailing slag subjected to drying, grinding and powder separation treatment and various reagents, and the reagents comprise an activating agent, an activating accelerant, a coagulant and a mineral surface activating agent. The tailing micro-powder comprises the following components in percentage by mass: 85%-90% of nonferrous metal ore dressing tailing slag, 5%-15% of an activating agent, 0.3%-1.2% of an activation accelerant, 0.3%-1.2% of a coagulant and 0.05%-0.2% of a mineral surfactant. The curing agent for full tailing slag filling is good in curing effect, high in cemented filling body strength, economical, environmentally friendly and good in industrial prospect and social benefit.
