摘要
尾矿是金属矿山开采选矿过程中排出的含有大量金属资源的固体废弃物,其综合利用率远低于其它大宗工业固体废弃物,它的综合化利用已成为全社会关注的焦点。在对福建省铁尾矿组分分析的基础上,从矿石的研磨工艺、尾矿的高效分级磁选等方面入手,阐述现有铁尾矿资源利用现状及形势,分析其产生的原因,指出了制约其发展的关键性问题,并提出“尾矿作为建筑材料、新型功能材料”等一系列适合当代“循环经济”发展的利用途径及解决对策。
Ore tailings are solid waste discharge from metal ore mining process,which has a lot of metal resources.However,its comprehensive utilization rate is much lower than other bulk industrial solid waste.Its comprehensive utilization has become the focus of the whole society.Based on the composition analysis of iron ore tailings in Fujian province,this paper starts with the grinding process of ore and high-efficiency grading magnetic separation of ore tailings.We explain the current status and situation of existing iron tailings resource utilization,analyze the causes,point out the key problems that restrict its development,and propose a series of utilization methods and solutions suitable for the development of contemporary“circular economy”such as“ore tailings as building materials and new functional materials”.
