Evaluation and development path of comprehensive utilization of mineral resources in China
The scale and structure of the reserves of various mineral resources in China are uneven,the large-scale single rich ore is insufficient,and there are many coexisting(or associated)and low-grade ores.This resource endowment determines the development route and mode of comprehensive utilization.After years of efforts,China has formed the world's most complete industrial system for mineral resource exploration,mining and dressing,smelting,processing and application,and the level of comprehensive development and utilization has been significantly improved.The oil and gas recovery rate is stable at a high level,the average coal recovery rate reaches 70%,the iron ore recovery rate and dressing recovery rate remain at about 80%,the mining and dressing indicators of nonferrous metal minerals are steadily rising,and the pace of comprehensive utilization of tailings and waste rocks has been accelerated,easing the pressure on the ecological environment.The supply capacity of mineral resources in our country has basically remained stable,playing an important role in ensuring economic and social development and peaceful operation.However,in recent years,the contradiction between supply and demand of mineral resources has remained prominent,with some minerals experiencing weak or declining reserves and production.The upstream pressure on the industrial chain has increased.Vigorously improving the efficiency and comprehensive utilization level of mineral resource development is an inevitable choice to ensure the safe supply of resources in China,and it is also a necessary path to promote the construction of ecological civilization and high-quality development in the mining industry.It is also an important carrier and lever for cultivating and developing new productive forces in the mining industry.This paper objectively evaluates the basic situation of the comprehensive utilization of mineral resources in China,analyzes the existing problems and prospects,and puts forward the development path of comprehensively constructing the five supporting systems of the comprehensive utilization of mineral resources.
