Process for manufacturing environment-friendly brick by replacing natural quartz sand with fine aggregate processed from industrial metallurgical tailings
The invention relates to a process for manufacturing an environment-friendly brick by replacing natural quartz sand with fine aggregate processed from industrial metallurgical tailings. The process comprises the following steps: 1) preparing the fine aggregate: transporting metallurgical tailings subjected to wet magnetic separation in an industrial metallurgical plant into a tailing stacking tank in an environment-friendly brick production field through a muck transport vehicle. According to the process for manufacturing environment-friendly brick by replacing natural quartz sand with fine aggregate processed from industrial metallurgical tailings, the tailings generated by industrial metallurgy are processed and then used for preparing the fine aggregate, so that the fine aggregate replaces the natural quartz sand in the raw materials of the existing environment-friendly brick, and the tailings are polished and screened, so that the smoothness and cleanliness of the tailings are consistent with those of river sand, the binding property with cement is strong, the tailings produced by industrial metallurgy are the by-product, such that the obtaining cost is low, the multi-stage screening is performed before the preparation so as not to exist the impurities affecting the brick body strength, and the advantages of high finished product strength and low cost are provided.
本发明涉及一种工业冶金尾渣加工细骨料替代天然石英砂的环保砖制造工艺，包括以下步骤：1)细骨料制备：通过渣土运输车将工业冶金厂经过湿法磁选后的冶金尾渣运输至环保砖生产现场的尾渣堆放池内。该工业冶金尾渣加工细骨料替代天然石英砂的环保砖制造工艺，通过将工业冶金所产生的尾渣处理后用于制备细骨料，使其替代现有环保砖原料中的天然石英砂，由于尾渣经过了打磨筛分处理，使其可以达到与河沙一致的光滑洁净性，与水泥的结合性强，而且由于工业冶金所产生的尾渣为副产品，其获取的成本低廉，而且在制备前已经经过了多级筛分，使得其中并不会存在影响砖体强度的杂质，具备成品强度高，成本低的优点。
