Method for producing building sand and tailing micropowder by using high-silicon tailing slag
The invention discloses a method for producing building sand and tailing micropowder by using high-silicon tailing slag, and relates to the technical field of tailing treatment. The method comprises the following steps: drying, sorting, crushing and screening the high-silicon tailing slag, dividing the high-silicon tailing slag into building sand with the particle diameter of 0.08-2.36 mm, adding an agent into the tailing slag with the particle diameter of less than 0.08 mm, grinding to prepare tailing micro powder, and using the produced building sand as a raw material of a dry-mixed mortar factory. The produced tailing micro powder is used as an admixture of concrete; according to the invention, the high-silicon tailings are used for producing the building sand and the tailing micro-powder, a very good effect is achieved on mine treatment of the tailings, the produced building sand can be applied to building material products, and the tailing micro-powder is mainly applied to various fields such as concrete mixing plants and cement plants as admixtures, so that the demand quantity is large, and the production cost is low. The treatment rate of the tailings is higher, and the method is an excellent scheme for solving the problem of tailings accumulation.
本发明公开了一种用高硅尾矿渣生产建筑用砂和尾矿微粉的方法，涉及尾矿处理技术领域。该方法包括将高硅尾矿渣通过烘干、分选、破碎和筛分，分成颗粒直径在0.08～2.36mm之间的建筑用砂，并将颗粒直径小于0.08mm的尾矿渣加剂研磨制成尾矿微粉，生产得到的建筑用砂作为干混砂浆厂的原料使用，生产得到的尾矿微粉则作为混凝土的掺合料使用；本发明利用高硅尾矿渣生产建筑用砂和尾矿微粉，对于矿山处理尾矿渣具有很好地作用，生产出的建筑用砂能够应用在建材产品，尾矿微粉主要应用在混凝土搅拌站和水泥厂作为掺合料等各种领域，因此需求量大，对于尾矿的处理速率更高，是解决尾矿堆积问题的极佳方案。
