Non-sintered antimony tailing brick and preparation process thereof
The invention provides a non-sintered antimony tailing brick and a preparation process thereof. The non-sintered antimony tailing brick consists of the following components in percentage by weight: 45%-60% of aggregate, 30%-45% of tailings, 8% of a cement-based material, 2% of water and 0.1% of an inorganic flocculant. According to a preparation method of the non-sintered antimony tailing brick, antimony after innocent treatment is taken as fine aggregate and powder, and mix proportion design is carried out to prepare a masonry material of which the strength meets the engineering practical application requirement and the seepage concentration of heavy metals and toxic substances meets the environmental protection requirement. Harmful components in the antimony tailings can be effectively cured by utilizing the inorganic flocculant and the cement-based material, so that tailings waste is harmless and can be recycled, and waste is turned into wealth.
本发明提供一种非烧结锑尾矿砖及其制备工艺。其中，所述非烧结锑尾矿砖由以下成分及含量组成：45％‑60％骨料、30％‑45％尾矿、8％水泥基材料、2％水和0.1％无机絮凝剂。一种非烧结锑尾矿砖的制备方法，将锑无害化处理后作为细骨料和粉料，进行配合比设计，配制出强度满足工程实际应用要求并且重金属及有毒物质渗出浓度满足环境保护需求的砌体材料。利用无机絮凝剂并结合水泥基材料可以对锑尾矿中有害成分进行有效固化，从而实现对尾矿废弃物的无害化和资源利用，做到变废为宝。
