Low-carbon cementing material for consolidation flotation of phosphate tailings as well as preparation method and application of low-carbon cementing material
The invention discloses a low-carbon cementing material for consolidation flotation of phosphate tailings as well as a preparation method and application of the low-carbon cementing material. The low-carbon cementing material comprises the following raw materials in parts by weight: 30-50 parts of slag powder, 35-45 parts of phosphorus slag powder, 5-10 parts of phosphogypsum and 5-15 parts of an exciting agent. The novel low-carbon cementing material disclosed by the invention is produced from industrial solid wastes, and the exciting agent is an alkaline exciting agent; compared with cement, the novel low-carbon cementing material consolidated superfine flotation phosphorus tailings have the advantages that the use amount is greatly reduced, the conveying property, the strength and the like of filling slurry are superior to those of the cement, the production cost is low, and the emission of carbon dioxide is reduced.
本发明公开了一种固结浮选磷尾矿的低碳胶凝材料及其制备方法和应用，包括下列重量份原料：矿渣粉30‑50重量份、磷渣粉35‑45重量份、磷石膏5‑10重量份，激发剂5‑15重量份；本发明的新型低碳胶凝材料采用工业固体废弃物生产得到，所述激发剂为碱性激发剂；新型低碳胶凝材料固结超细浮选磷尾砂相比水泥用量大幅降低，充填料浆输送性、强度等优于水泥，且生产成本低，减少了二氧化碳排放。
