邯邢铁矿尾矿中元素的粒度效应和形态分布特征:资源和环境意义
Grain size effect and chemical speciation of elements in tailings from the Han-Xing iron deposit:Implications for resource utilization and environmental protection
摘要
Abstract
Despite bearing valuable recyclable elements,mine tailings pose environmental risks.However,there is a lack of studies on the geochemical characteristics of tailings in China and abroad,hindering their appropriate treatment and reuse.This study collected tailing samples from the Han-Xing Iron deposit in Hebei Province,China and conducted the analysis and tests of these samples.This study determined the concentrations and chemical speciation(i.e.,exchangeable,carbonate-bound,Fe-Mn oxide-bound,organic-bound,and residual forms)of elements including Fe,Co,S,Cu,and Zn in tailing particles with varying grain sizes.Accordingly,it explored the implications for the exploitation and utilization of tailing resources,along with the assessment of environmental risks.This study provides deeper insights into the geochemical characteristics of tailings,producing positive impacts on the exploitation and utiliza-tion of tailing resources,as well as the prevention of environmental risks.关键词
