Recycling method of fine-grained tailing sand
The invention provides a recycling method of fine-grained tailing sand. Tailing sand, clay and limestone are used as raw materials to produce cement clinker for roads. According to the components of the raw materials, in combination with change conditions of compounds generated before and after a chemical reaction, association rules are established, the blending proportion of the raw materials isaccurately calculated based on the association rules, the cement performance and quality are controlled through parameter adjustment, fine-grained tailing sand is selected, the grinding process is reduced, and the compatibility among all the components is good. The advantages of iron tailing components, the delayed coagulation effect of ardealite and the later strength of fly ash reinforced cementare fully utilized, it is ensured that the cement has good performance in road engineering use, meanwhile, solid waste tailings are utilized to the maximum extent, resource recycling and efficient utilization of tailing sand are promoted, and recycling of wastes, high efficiency of resources and environmental protection of achievements are achieved.
本发明提供一种细粒度尾矿砂的回收利用方法，将尾矿砂与粘土、石灰石作为原材料生产道路用水泥熟料，根据原材料的组分，结合化学反应前后生成化合物的变化情况，建立关联规则，基于此，精确的计算原材料掺配比例，并通过参数调整，控制水泥性能和质量，选择细粒度的尾矿砂，减少研磨工序，各组分之间相容性较好。本发明充分利用铁尾矿组分优势、磷石膏缓凝作用以及粉煤灰增强水泥后期强度，确保在道路工程使用中具有较好性能，同时最大程度利用固体废弃物尾矿，促进尾矿砂的资源循环高效利用，使废物资源化、资源高效化、成果环保化。
