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

Abstract

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.
