Filling curing agent for high-sulfur iron tailing and preparation method thereof
The invention provides a filling curing agent for high-sulfur iron tailing. The filling curing agent is prepared from the following raw materials in parts by weight: 40-80 parts of mineral powder particles, 5-30 parts of steel slag powder particles, 5-25 parts of Portland cement clinker, 1-3 parts of anhydrous sodium sulphate, 5-25 parts of fly ash and 2-10 parts of mirabilite. The preparation method comprises the following steps: grinding; drying; and preparing. The filling curing agent is high in early strength, low in cost and good in the curing effect on the iron tailing with high sulfur content.
一种高硫铁尾砂充填固化剂，由以下重量份的原料制成：矿粉微粒40‑80、钢渣粉微粒5‑30、硅酸盐水泥熟料5‑25、元明粉1‑3、粉煤灰5‑25、芒硝2‑10。其制备方法，包括以下步骤：粉磨；烘干；配制。本发明早期强度高；成本低；对高硫含量的铁尾砂固化效果好。
