Iron tailing sintered brick and preparation method thereof
The invention discloses an iron tailing sintered brick and a preparation method thereof. The iron tailing sintered brick is prepared from the following raw materials in percentage by mass: 55%-65% ofiron tailings, 10%-30% of fly ash and 10%-30% of waste glass. According to the method, solid waste is used as a raw material, a green sustainable development utilization way is provided for treatmentand disposal of the solid waste, secondary pollution is avoided in the preparation process, and the requirements for clean production and environmental protection are met. The sintered brick has the advantages of low water absorption, high strength and low heavy metal leaching concentration.
本发明公开了一种铁尾矿烧结砖及其制备方法。铁尾矿烧结砖包括如下按质量百分比计的原料制备得到：铁尾矿55％～65％，粉煤灰10％～30％，废弃玻璃10％～30％。本发明是以固体废弃物做为原料，为固体废弃物的处理与处置提供了绿色可持续发展的利用途径，制备过程无二次污染，达到了清洁生产、绿色环保的要求。本发明的烧结砖具有吸水率低、强度高、重金属浸出浓度低的优点。
