摘　　要：伴随矿产资源的开发利用,产生的大量尾矿,造成能源浪费和环境污染。由于尾矿中蕴藏多种有价元素和可利用的成分,因此尾矿作为一种潜在二次资源的综合再利用,既可以创造新的社会财富,又消除了对环境的破坏,成为治理矿山废弃物的有效途径。本文通过综合利用尾矿中的有用元素;尾矿作为硅酸盐原料进行整体利用,制备绿色无机材料;用作充填材料3个方面,详细介绍了尾矿利用的技术进展。With an exploitation of the mineral resource, the by-product massive tailing creates the energy waste and the environmental pollution. Due to the containing valuable elements and the availability of ents,tailing is a potential secondary resource. Recycle of tailings creates the new social wealth and eliminates the environment destruction, become an ideal way to deal with the mine waste. This paper report the technology progresses in the reuse of tailings, focused on three aspects ;reuse of the valuable elements, comprehensive utilization as silica powders to prepare inorganic eco-material, as filling materials.
