Preparation method of modified lithium slag-based mine filling material
The invention provides a preparation method of a modified lithium slag-based mine filling material, which comprises the following steps of: performing mechanical activation, chemical activation and the like on various solid wastes such as alkaline residues, causticized white mud, desert aeolian sand, molybdenum tailings, steel slag, stainless steel slag, vanadium-titanium slag, circulating fluidized bed fly ash, circulating fluidized bed slag, electrolytic manganese slag, desulfurized gypsum, lithium slag and the like to prepare the modified lithium slag-based mine filling material. The preparation method can solve the problems of harmlessness, reduction and recycling of a large amount of industrial solid wastes, promotes the synergistic utilization of steel solid wastes, coal-based solid wastes, agricultural solid wastes, chemical solid wastes and non-ferrous metallurgical solid wastes, and has a wide application prospect in large-scale replacement of Portland cement cementing materials. And a foundation is laid for application in mineral engineering.
本发明提供一种改性锂渣基矿井充填料制备方法，利用碱渣、苛化白泥、沙漠风积砂、钼尾矿、钢渣、不锈钢渣、钒钛矿渣、循环流化床飞灰、循环流化床炉渣、电解锰渣、脱硫石膏、锂渣等，等多种固废，通过机械力活化和化学活化等方式，提升固废的火山灰活性，制备全固废膏体矿井充填料，不仅能够解决大宗工业固废的无害化、减量化和资源化难题，推进钢铁固废、煤基固废、农业固废、化工固废、有色冶金固废的协同利用，为大规模替代硅酸盐水泥胶凝材料，在矿业工程中的应用奠定基础。
