Comprehensive evaluation of the development,utilization and protection of low-grade iron ore resources:Taking low-grade iron ore in Wulate Qianqi,lnner Mongolia as an example
Iron ore is the basic raw material for the iron and steel industry,and is one of China's strategic minerals.China's iron ore resources are characterized by low grade,small scale,need for beneficiation and high cost,with insufficient domestic supply security capacity and rising external dependence.It is essential to carry out a comprehensive evaluation of the development,utilization and protection of China's low-grade iron ore resources.This paper analyzes the current situation of the development and utilization of low-grade iron ore resources in Wulate Qianqi,Inner Mongolia,and evaluates the economic,environmental and social benefits of mining and utilizing mineral resources.Based on the evaluation of the three major benefits,it points out that the mining of iron ore resources below the minimum industrial grade index is profitable,and the break-even grade of the mine is about 4.37%～7.47%,meeting the average grade of investment return of 5.55%～9.83%.The cost of managing and restoring iron ore resources that are below the minimum industrial grade index is less than the amount of the management fund,and the fund management measures are compliant and reasonable.On this basis,the effective path for the green and low-carbon transformation of low-grade iron ore in Wulate Qianqi,Inner Mongolia is proposed as"intensive development of the industrial chain with low-carbon extension",providing theoretical references for regional government decision-making facing constraints of"economy-resources-environment".
