一种铁尾矿干堆用固化剂及其制备方法
摘要：
本发明公开一种铁尾矿干堆用固化剂及其制备方法，属于矿山安全技术领域。该固化剂是由固化剂熟料以及激发剂组成，固化剂熟料的基本组成及其质量份数为：CaO：46～50份、MgO：12～18份、SiO2：20～25份、Al2O3：8～12份、矿化剂：1～2份。制备该固化剂首先将富含CaO以及MgO的原料与同时富含Al2O3以及SiO2的原料以及矿化剂后进行研磨，然后将研磨制得的磨制粉体喂入成球盘中制成固化剂熟料粉体，最后向固化剂熟料粉体中加入激发剂粉体经过搅拌混合均匀后制得铁尾矿干堆用固化剂。本发明制备的固化剂固化能力强且原料成本较低，具有大规模推广运用的良好前景。
摘要（英）：

The invention discloses a curing agent for a dry iron tailing stack and a preparation method of the curing agent, belonging to the technical field of mine safety. The curing agent is composed of curing agent clinker and an excitant, wherein the curing agent clinker comprises the basic components in parts by mass: 46-50 parts of CaO, 12-18 parts of MgO, 20-25 parts of SiO2, 8-12 parts of Al2O3 and 1-2 parts of mineralizing agent. The preparation method comprises the steps of firstly, grinding a CaO and MgO enriched raw material, an Al2O3 and SiO2 enriched raw material and the mineralizing agent; then, feeding the ground powder into a balling dish to prepare curing agent clinker powder; and finally, adding excitant powder into the curing agent clinker powder, stirring and uniformly mixing to obtain the curing agent for the dry iron tailing stack. The curing agent prepared by the invention is strong in curing capacity, relatively low in raw material cost and favorable in large-scale popularization and application prospects.
