Composite curing agent material, preparation method thereof and tailing curing method
The invention discloses a composite curing agent material, a preparation method thereof and a tailing curing method. The composite curing agent material is composed of water-quenched slag, mineral powder, cement clinker, fly ash and quick lime, and the composite curing agent is prepared through the preparation method of the composite curing agent material. Mixing the tailings, ferric sulfate and water to obtain tailing mortar, and mixing and stirring the tailing mortar and the composite curing agent to obtain the tailing solidified body. According to the tailings curing method provided by the invention, the consumption of cement in the tailings curing process can be reduced, the carbon emission is indirectly reduced, and meanwhile, the curing effect of heavy metals in the tailings is enhanced.
本发明公开一种复合固化剂材料及其制备方法和尾砂固化方法。该复合固化剂材料由水淬渣、矿粉、水泥熟料、粉煤灰和生石灰组成，并通过复合固化剂材料的制备方法制备得到复合固化剂。将尾砂、硫酸铁和水混合，制得尾砂浆，将尾砂浆与复合固化剂进行混合搅拌，制得尾砂固化体。本发明提供的尾砂固化方法，可减少尾砂固化过程中水泥的消耗量，间接降低碳排放量，同时增强尾砂中重金属固化效果。
