Heavy metal curing agent and method for tungsten tailing resource utilization
The invention discloses a heavy metal curing agent and method for tungsten tailing resource utilization. The curing agent comprises, by weight, 30-70% of activated tungsten tailings, 5-20% of lime, 5-10% of sodium silicate and 20-40% of cement. The curing agent is uniformly mixed, is heated at 90-110 DEG C for 4-6 hours for drying, and finally the curing agent is ground by using a grinding machine until the specific surface area exceeds 300 m<2>/kg. A method for activating the tungsten tailings is characterized in that by taking the mass of the tungsten tailings as a standard, the dosage of an activating agent is 0.01-0.5%; and the activating agent is added in the form of a solution and comprises sodium hexametaphosphate, stearic acid, semi-hydrated gypsum and polymerized organic polyol, the mixture is mixed and ground for a certain time through a mill, and activated tungsten tailings are obtained. The curing agent is prepared from the mine activated tungsten tailings, the lime, the sodium silicate and the cement, the preparation process is short in time consumption and low in energy consumption, the consumption of the cement can be effectively reduced, and the consumption of energy and resources is reduced.
本发明公开了一种钨尾矿资源化利用的重金属固化剂及固化方法，固化剂配比组成为：30～70％活化钨尾矿、5～20％石灰、5～10％泡花碱和20～40％水泥；固化剂混合均匀后在90℃～110℃加热4～6小时干燥，最后将固化剂采用磨机粉磨至比表面积超过300m2/kg；所述活化钨尾矿的方法为：以钨尾矿的质量为基准，活化剂的用量：0.01％‑0.5％；活化剂以溶液形式加入，活化剂为：六偏磷酸钠、硬脂酸、半水石膏和聚合有机多元醇，混合后采用磨机粉磨一定时间，获得活化钨尾矿；本发明采用矿山活化钨尾矿、石灰、泡花碱和水泥制备固化剂，制备工序耗时短，能耗较低，且能有效减少水泥的用量，减少能源和资源的消耗。
