Curing agent produced from solid waste residues and used for filling full tailing slag and application of curing agent
The invention discloses a curing agent produced from solid waste residues and used for full-tailing slag filling and application of the curing agent, and belongs to the technical field of filling curing agents, the curing agent is prepared from, by mass, 20%-30% of cement, 2%-8% of gypsum powder and lime powder, 30%-40% of slag powder and 30%-40% of lithium slag powder, the lithium slag powder is superfine slag powder obtained after water-quenched blast furnace slag is dried, ground and subjected to powder separation, and the lithium slag powder is obtained by conducting filtration and purification on slag left after lithium ore is subjected to roasting and mineral water separation to obtain lithium slag, then conducting drying, grinding and powder separation on the lithium slag, adding a surfactant and an activating agent in the grinding process, and conducting mixing and grinding. The curing agent for full tailing slag filling is good in curing effect, high in cemented filling body strength, economical, environmentally friendly and good in industrial prospect and social benefit.
本发明公开了一种利用固废渣生产的全尾矿渣充填用固化剂及其应用，属于充填固化剂技术领域，包括以下按质量配比的原料：水泥20％‑30％，石膏粉和石灰粉2％‑8％，矿渣粉30％‑40％，锂渣粉30％‑40％，所述矿渣粉为铁厂炼铁时产生的高炉炉渣，是将水淬高炉炉渣进行烘干、研磨和选粉后得到的超细矿渣粉，所述锂渣粉是将锂矿经过焙烧、水选矿物后剩余的渣经过过滤净化得到锂渣后，再将锂渣经过烘干、研磨和选粉，并在研磨过程加入表面活性剂和激活剂进行混合研磨获得的，本发明公开的一种固化效果好、胶结充填体强度高、经济环保且具有良好工业前景和社会效益的全尾矿渣充填用固化剂。
