Phosphorite tailing resource utilization method
The invention relates to the technical field of phosphorite tailing recycling, and discloses a phosphorite tailing resource utilization method which comprises the following steps: 1) preparing a manufacturing mold; (2) preparing required materials; 3) preparing a stirrer; 4) starting the stirrer; 5) preliminarily adding materials in the stirrer; (6) adding materials into the stirrer again; 7) adding the material into the mold; 8) curing the concrete test block; and 9) performing a performance test. In conclusion, by analyzing the chemical composition of the phosphorite tailings, the phosphorite tailings can partially replace the fine aggregate in the concrete, and then the phosphorite tailings and the coarse sand are proportioned in a certain range, so that relatively proper fine aggregate grading is achieved and used for preparing various types of concrete, and resource utilization of the phosphorite tailings is completed; pollution caused by solid waste stacking is reduced, and the method has the advantages that energy is saved, emission is reduced, harm is turned into benefit, and the preparation cost of the concrete is reduced. The bending toughness and the impact toughness of the matrix concrete can be improved.
本发明涉及磷矿尾渣回收技术领域，且公开了一种磷矿尾渣资源化利用方法，包括以下步骤：1)制作模具准备；2)所需材料准备；3)搅拌机准备；4)启动搅拌机；5)搅拌机内初步增加材料；6)搅拌机内再次增加材料；7)材料加入模具内；8)养护混凝土试块；9)进行性能测试。综上所述，本发明通过对磷矿尾渣化学组成的分析，磷矿尾渣可以部分代替混凝土中的细骨料，进而将磷矿尾渣与粗砂进行一定范围的配比，达到较适宜的细骨料级配，用于配置各类混凝土，完成对磷矿尾渣进行资源化的利用，不仅有利于降低减少固体废弃物堆放导致的污染，具有节能减排，变害为利及降低混凝土制备成本的优点。可以提升基体混凝土的弯曲韧性和抗冲击韧性。
