铁尾砂资源化利用及铁矿区土壤修复技术研究进展OA

With the continuous exploitation of iron ore resources,the amount of iron tailings has been increasing year by year,and its comprehensive utilization rate is low.It not only occupies a large amount of land resources,but also causes environmental problems such as soil heavy metal pollution.This article summarizes the current status of resource utilization for iron tailings in the industrial and agricultural fields in China,and points out the problems existing in the resource utilization of iron tailings.The advantages and disadvantages of soil pollution remediation tech-nologies such as physical remediation,chemical remediation,biological remediation and combined remediation techno-logies in iron mining areas were summarized,and the countermeasures for soil pollution remediation in iron mining areas were put forward in order to provide references for the high-quality development of iron ore industry in China.
