Titanium extraction tailing-based full-tailing filling cementing material and preparation method thereof
The invention discloses a titanium extraction tailing based full tailing filling cementing material and a preparation method thereof, the titanium extraction tailing based full tailing filling cementing material comprises 50 wt%-65 wt% of titanium extraction tailings, 18 wt%-25 wt% of titanium gypsum, 5 wt%-20 wt% of cement, 3 wt%-10 wt% of lime and 1 wt%-3 wt% of a modifier; wherein the modifier is formed by compounding sodium sulfate, copperas and sodium metaaluminate. The titanium gypsum, the cement and the lime are combined and utilized, and a small amount of modified materials are supplemented, so that the problem of resource utilization of titanium extraction tailings and titanium gypsum solid waste treatment is solved, and the titanium extraction tailing-based full-tailing filling cementing material which is high in early strength, good in filling body stability, good in chlorine fixing effect, good in flowing property and simple and feasible in processing technology is prepared.
本发明公开了一种提钛尾渣基全尾砂充填胶凝材料及其制备方法，该提钛尾渣基全尾砂充填胶凝材料，包括50wt％‑65wt％的提钛尾渣、18wt％‑25wt％的钛石膏、5wt％‑20wt％的水泥、3wt％‑10wt％的石灰和1wt％‑3wt％的改性剂；其中，所述改性剂由硫酸钠、绿矾、偏铝酸钠复配而成。本发明结合利用钛石膏、水泥和石灰并辅以少量改性材料，解决提钛尾渣和钛石膏固废处理的资源化利用问题，制备出早期强度高、充填体稳定性好、固氯效果佳、流动性能好且加工工艺简单易行的提钛尾渣基全尾砂充填胶凝材料。
