Mining phosphogypsum modifier and preparation method thereof
The invention discloses a mine phosphogypsum modifier, and relates to the field of mine filling materials, the mine phosphogypsum modifier comprises the following components by weight: 50-80 parts of mineral powder, 20-40 parts of steel slag, 20-40 parts of red mud, 5-8 parts of aluminum salt, and 0.2-0.5 part of a dispersant; the phosphogypsum modifier is prepared from the component materials according to the designed steps and method. The invention aims to solve the influence of soluble phosphorus and soluble fluorine in ardealite on underground water quality of mines. The mine phosphogypsum modifier prepared by the invention can greatly reduce the cost, treat wastes with wastes, realize solid waste recycling and high-valued application, can solve the problem of pollution of soluble impurities in phosphogypsum to phosphogypsum filling bodies and mine underground water quality, and has remarkable environmental protection, economic and engineering application values.
本发明公开了一种矿用磷石膏改性剂，涉及矿山充填材料领域，按重量份计，包括以下组分：矿粉50‑80份，钢渣20‑40份，赤泥20‑40份，铝盐5‑8份，分散剂0.2‑0.5份；将上述的组分材料按照设计的步骤方法得到磷石膏改性剂。该发明的目的是解决磷石膏中可溶磷、可溶氟对矿山地下水质的影响；通过该发明制备的矿用磷石膏改性剂，能够大幅度降低成本，以废治废，实现固废资源化和高值化应用，能够解决磷石膏中可溶杂质对磷石膏充填体和矿山地下水质的污染问题，具有显著的环保、经济及工程应用价值。
