Characteristics and Comprehensive Utilization Practices of Stripping Waste Rocks from Vanadium-Titanium Magnetite

中文摘要英文摘要

这是一篇矿业工程领域的论文.钒钛磁铁矿铁矿采选过程中产生大量剥离废石,主要分为三类:剥离土物料、剥离岩石物料和表外矿.由于风化、雨淋等作用,废石中的有毒有害元素会对周围环境造成二次污染.废石资源的回收再利用大有裨益,能够提高资源利用率并有效减少土地占用和环境污染.因此,本文对三种剥离废石的特性进行了系统分析,并以此为依据,对其综合利用途径分别进行分析和总结.剥离土物料和剥离岩石物料可以根据其风化程度,作为尾矿坝筑坝材料、建筑砂石用料等,变废为宝;表外矿可以通过预选提高品位,进行回收利用.本文能够为钒钛磁铁矿剥离废石的进一步综合利用提供参考借鉴,从而大幅提高钒钛磁铁矿矿资源综合利用水平.

This is an article in the field of mining engineering.The vanadium and titanium magnetite iron ore mining process generates a large amount of stripped waste rock,which is divided into three main categories:stripped soil material,stripped rock material and off-site ore.Due to weathering,rain and other effects,the toxic and harmful elements in stripped rock will cause secondary pollution to the surrounding environment.The recycling of stripped rock resources is of great benefit,which can improve the utilization rate of resources and effectively reduce land occupation and environmental pollution.Therefore,in this paper,the characteristics of three kinds of waste rock are systematically analyzed,and based on this,the comprehensive utilization ways are analyzed and summarized.The stripped soil and stripped rock materials can be used as tailings dam construction materials and construction sand and stone materials to turn waste into treasure.The off-balance sheet ore can be recycled by pre-concentration to improve its grade.This paper can provide reference for further comprehensive utilization of vanadium titanium magnetite stripped waste materials,so as to greatly improve the comprehensive utilization level of vanadium titanium magnetite ore resources.
