The invention relates to a golden gold tailing curing agent, a preparation method and a use method, and belongs to the technical field of environmental engineering. The golden gold tailing curing agent comprises phosphate ore, quartz tailing slag, carbide slag and coagulated stone according to a mass ratio of (1-3) : (1-3) : (1-3.5) : (1-4); the preparation method comprises the following steps: respectively washing, drying, crushing and grinding the phosphate ore, quartz tailing slag and carbide slag, and grinding and treating the coagulated stone; and uniformly mixing all the components. Theusing method of the gold tailing curing agent comprises the steps that gold tailings and the added gold tailing curing agent are stirred to be uniform in proportion, curing is achieved, the compressive strength can reach 61-82.8 KPa after the gold tailings and the added gold tailing curing agent are stacked in a normal-temperature and normal-pressure field for three days, and the pH of leachate ranges from 6.9 to 8.35. The gold tailing curing agent adopts solid waste as a raw material, treats waste with waste, and is wide in raw material source and low in cost, and the cured golden gold tailings are used as soil for road filling.
一种黃金尾矿固化剂、制备方法与使用方法，属于环境工程技术领域，黃金尾矿固化剂中，磷矿石、石英尾矿渣、电石渣和凝石按质量比为(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。黄金尾矿固化剂的使用方法包括：黄金尾矿与添加的黃金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界于6.9～8.35。本发明的黄金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。固化后的黃金尾矿作为道路填筑用土。
