The invention discloses an iron ore tailing curing agent, and a preparation method and a use method thereof, belonging to the technical field of environmental engineering. In the iron ore tailing curing agent, a mass percentage ratio of phosphate ore to quartz tailing slag to carbide slag to glued stone is (1-3): (1-3): (1-3.5): (1-4). The preparation method comprises the steps that the phosphateore, the quartz tailing slag and the carbide slag are washed with water, dried, crushed and ground, the glued stone is ground and treated, and then the treated components are uniformly mixed in proportion. The use method of the iron ore tailing curing agent comprises the steps that iron ore tailings and the added iron ore tailing curing agent are uniformly stirred in proportion, so curing is achieved, compressive strength can reach 61-82.8 KPa after a mixture of the iron ore tailings and the added iron ore tailing curing agent is stacked in a normal-temperature and normal-pressure field for three days, and the pH value of leachate ranges from 6.9 to 8.35. The iron ore tailing curing agent adopts solid waste as a raw material, so the waste is treated with the waste, and raw materials are wide in source and low in cost. The cured iron ore tailings are used as soil for road filling.
一种铁矿尾矿固化剂、制备方法与使用方法，属于环境工程技术领域，铁矿尾矿固化剂中，磷矿石、石英尾矿渣、电石渣和凝石按质量百分比为(1～3)∶(1～3)∶(1～3.5)∶(1～4)，其制备方法包括：分别对磷矿石、石英尾矿渣及电石渣进行水洗、烘干、破碎、碾研，凝石也经碾研，处理后，按比例混合均匀。铁矿尾矿固化剂的使用方法包括：铁矿尾矿与添加的铁矿尾矿固化剂按比例搅拌均匀，实现固化，并在常温、常压场地中堆积三天后抗压强度能够达到61～82.8KPa，浸出液的pH介于6.9～8.35。本发明的铁矿尾矿固化剂采用固体废弃物为原料，以废治废，原料来源广泛，成本低。固化后的铁矿尾矿作为道路填筑用土。
