What are the potential and development prospects of comprehensive utilization of mineral resources in China? National mineral resources saving and comprehensive utilization report (2014) recently compiled by China National Institute of land and resources economics shows that the comprehensive utilization of mineral resources in China has great potential and broad prospect. Mining enterprises through technological progress and improvement of process and equipment, and make an inventory of the large number of difficult to use mineral resources, has huge resource benefits, economic benefits, environmental benefits and social benefits, but also enhance the mining enterprise resource comprehensive utilization of space.
Technological progress has become the driving force
Years of practice has proved that technological progress has become the primary power to improve the conservation and comprehensive utilization of mineral resources. In recent years, with the attention of the state and enterprises on the comprehensive utilization of mineral resources, the central, local and enterprises continue to increase investment in technology innovation. To Chinese Academy of Geology and mineral resources comprehensive utilization Institute and Chinese Academy of Geological Sciences Zhengzhou mineral comprehensive utilization research units on behalf of research around the national shortage minerals and difficult to use mineral, vigorously carry out technological innovation, the savings for mineral resources of our country and comprehensive utilization provides strong technical support. At the same time, the Ministry of land and resources and the Ministry of finance also set up special mineral resources saving and comprehensive utilization of special, encourage and support mining enterprises to carry out complex difficult to use resources, mining and metallurgical technology research, research and development of mineral resources utilization and conservation and recycling technology, greatly improving domestic mineral resources comprehensive utilization efficiency and effectiveness.
It is worth mentioning that, in recent years, the Ministry of land and resources to take a variety of measures to promote the conservation of mineral resources and comprehensive utilization of technology to promote the application of work. In 2012, the Ministry of land and resources introduced "on the promotion of advanced and applicable technologies to improve mineral resources saving and comprehensive utilization level of the notice", the establishment of the promotion of advanced and applicable technologies directory release system, and has divided into two batches released 99 mineral resources saving and comprehensive utilization of advanced technology, to accelerate the transformation of advanced technology, plays an important role in promoting. This year, the Ministry of land and resources to continue to carry out the third batch of advanced application of the recommended selection of the work.
"From the current perspective, the advanced application of technology selection and promotion mechanisms are becoming increasingly sophisticated, the release of the 99 technologies are through the relevant areas of expert selection, demonstration. From the application of these technologies in the mine, its penetration rate and promotion efficiency continue to improve, to improve the level of comprehensive utilization of mineral resources, promote scientific and technological innovation has played a leading role." The mineral reserves division of Ministry of land and resources director Xu Dachun said, with the two batch of advanced technology selection, based on the relevant support policy improvement, Ministry of land and resources to take a variety of forms, release of advanced and applicable technologies, widely publicize the significance and effectiveness of the popularization and application of advanced technology, open access to advanced information technology in mining enterprises the mining industry to create advanced technology promotion atmosphere, let the advanced technology can find application to mine, mining enterprises need to find suitable technology, advanced technology has broken the dispersion, closure and application situation of the low rate, high conversion rate and popularity rate of advanced technology, which plays an important role in improving the level of the development and utilization of mineral resources, win government departments, industry associations, research institutes, mining enterprises alike.
"Mineral resources saving and comprehensive utilization" in 12th Five-Year "planning" shows that China's mineral resources mining new technologies continue to get a breakthrough, some of the important mineral resources mining technology to achieve or close to the world advanced level. Carbon dioxide flooding technology, multi branch wells, a fully mechanized comprehensive mechanized mining technology, coal mining technology achievements conversion gangue has been industrialized application; steep slope mining technology, sublevel caving mining and filling mining technology such as a large number of new technologies to promote the application of fine grinding of fine; magnetic separation, discarding coarse tailings, fine - magnetic - reverse flotation technology, the iron concentrate grade and recovery rate reached a higher level; efficient new flotation reagents, ramified flotation, electrochemical control flotation and flash flotation process, improve the separation efficiency of non-ferrous metal ore dressing Bayer process; industrial application the bauxite resources, make our country a large number of aluminum silicon ratio is less than 5 for full use; application of gold heap leaching technology, greatly reduces the production cost of gold; multi crystalline graphite grinding Mine, multi section of the selection process improvement, improve the recovery rate of graphite and concentrate grade.
"Mineral resource conservation and comprehensive utilization of the development and application of advanced and applicable technologies, to improve China's mineral resources' third rate '(mining recovery rate and ore dressing recovery rate and resource comprehensive utilization rate) level and mining enterprises of economic benefit, social benefit to an important role in promoting."
