Phosphorus tailing curing treatment method and application thereof
The invention discloses a phosphate tailing solidification treatment method and application thereof, and the phosphate tailing solidification treatment method comprises the following steps: S10, cement, phosphate tailings and loess are uniformly mixed to obtain a dry mixture; s20, uniformly mixing the dry mixture with water to obtain a wet mixture; and S30, after the wet mixed material is subjected to film pressing forming, demolding and curing treatment are conducted, and a phosphate tailing cured body is obtained. Phosphorus tailings are solidified through cement and loess and then used as a building material, waste residues generated by phosphorite beneficiation serve as main raw materials and play a role in gelling and aggregate in the solidified body manufacturing process, the solidified bodies which can be stacked and are environmentally friendly are produced, the phosphorus tailings can be rapidly solidified and recycled in a large scale, and the resource utilization rate of the phosphorus tailings is increased. No anti-seepage film needs to be laid or a special tailing pond needs to be built, investment is reduced, cost is saved, and meanwhile environmental risks are reduced.
本发明公开了一种磷尾矿固化处理方法及其应用，所述磷尾矿固化处理方法包括以下步骤：S10、将水泥、磷尾矿及黄土混匀，得干混料；S20、将干混料与水混匀，得湿混料；S30、将湿混料经压膜成型后，脱模，固化处理，得磷尾矿固化体。通过将磷尾矿经水泥和黄土固化后作为建筑材料使用，采用的主要原料为磷矿选矿产生的废渣，在固化体制作过程中，起胶凝和骨料的作用，生产可以堆放的、对环境友好的固化体，可以快速地、大批量地对磷尾矿进行固化并资源化利用，无需铺防渗膜及建造专门的尾矿库，减少投资，节约成本，同时减少环境风险。
