Abstract: The main objects of the ultra-low-grade ore exploitation in Inner Mongolia are gold,lead,zinc and iron ore,which are mainly in Bayannaoer,Baotou,Wulanchabu and Chifeng.The production capacity is accounting for about 57.72%,which have been more than half.But the regions exploiting the ultra-low-grade ore in Inner Mongolia are in ecologically sensitive area,and there have been serious problems such as serious ecological damage that difficult to recover,gravel emissions large that difficult to manage,policy lag,backward production capacity,social risk that difficult to prevent and so on.Based on the current situation of ultra-low-grade mineral resources exploitation and utilization,and combined "innovation,coordination,green,open,sharing" five concept of "capacity to destocking,deleveraging,lower taxes to make up the short board" five task under the new situation,this paper put out some suggestions,such as scientific exploiting and using ultra-low-grade mineral resources base on innovation and the key technology breakthrough,adherence to the bottom line of the ecological environment by improving the access threshold for mining,effectively regulating the resources supply to achieve sustainable development of mining,effectively preventing various social risks by deepening the supply-side reform and optimization of policy measures.These suggestions have certain practical significance for the development and utilization of ultra-low-grade resources in Inner Mongolia and China.
