Superfine tailing filling cementing material mainly prepared from copper slag and fly ash and filling material of superfine tailing filling cementing material
The invention provides a superfine tailing filling cementing material mainly prepared from copper slag and fly ash and a filling material thereof. The cementing material comprises 30-50 parts of copper slag micro powder, 20-40 parts of fly ash, 15-20 parts of cement clinker, 6-13 parts of high-strength gypsum powder and 2-4 parts of an alkali activator. The filling material comprises the cementing material and superfine tailings. The preparation method comprises the following steps: grinding copper slag, mixing the ground copper slag with water to form slag slurry, performing mechanical activation on the slag slurry, and drying the activated slag slurry to prepare the copper slag micro powder; the copper slag micro powder and fly ash are used as main raw materials to form a cementing material suitable for superfine tailing filling under the action of auxiliary materials such as cement clinker and gypsum powder and an alkaline activator, so that the tailing filling utilization rate can be increased, the problems of long setting time and high filling cost of a superfine tailing filling body can be solved, and the filling effect of the superfine tailing filling body is improved. And comprehensive utilization of waste residue resources is realized.
本发明提供了一种以铜炉渣和粉煤灰为主的超细尾砂充填胶凝材料及其充填料。该胶凝材料包括铜炉渣微粉30‑50份、粉煤灰20‑40份、水泥熟料15‑20份、高强石膏粉6‑13份、碱性激发剂2‑4份；充填料包括该胶凝材料和超细尾砂。本发明通过将铜炉渣研磨后与水混合形成渣浆，再对渣浆进行机械力活化，然后将活化后的渣浆烘干，制备了铜炉渣微粉；该铜炉渣微粉与粉煤灰作为主要原料，在水泥熟料、石膏粉等辅料以及碱性激发剂的作用下，形成了适用于超细尾砂充填胶凝材料，不仅能提高尾砂充填利用率，还能解决超细尾矿充填体凝结时间长、充填成本高的难题，并实现废渣资源的综合利用。
