摘要
随着铁矿资源的不断开采利用,作为原铁矿选矿过程中的必然产物——铁尾矿,因其排放量大、利用率低的特点,已成为世界范围内的主要固体废弃物之一,如何提高铁尾矿的利用率一直是各国学者研究的重点方向。对国内外铁尾矿的物化特点、排放量、引起的危害、处理途径和综合利用情况做出了综述性研究,综合国内外对铁尾矿的利用情况,将铁尾矿运用到建筑材料中将会对铁尾矿利用率和建筑成本等起到重大作用。
With the continuous exploration of iron ore resources, the iron tailings, as the inevitable byproduct of the process of the origin iron ore selection, has become one of the main solid waste around the world because of its large output and low utilization ratio.How to maximize its utilization ratio has been an important issue of scholarly research from various countries.It outlines the physical and chemical properties, emissions, hazards and the comprehensive utilization of iron ore railings.From iron tailings＇ utilization situation,the iron tailings would be applied to building materials and construction will play a major role in improving tailings＇ utilization and reducing the costs of buildings.
