Rare comments clean technology implementation plan

Last weekend, the organization prepared by the Ministry of Industry , designed to accelerate the application of rare earth advanced clean production technologies and promotion of cleaner production level to improve the industry , " rare earth industry clean production technology implementation plan ( draft)" publicly and began to solicit opinions . This marks the prelude of rare earths from technology developed to eliminate the pollution source control chaos has been opened, large rare earth industry efforts to implement environmentally friendly technological transformation is also coming.

According to Dean of College of Inner Mongolia University of Science and Technology of Rare Earth Yin Zhang , the " solutions " proposed to promote four new technology , you can basically solve soil erosion , waste of resources and the " three wastes" issues such as excessive emissions caused by the production of rare earth enterprises . Currently, this technology has several Jiang Su Guosheng Rare Earth , respectively , Baoding rare earth materials pilot plant , new materials Grirem AG , Guangdong Zhujiang Rare companies and other enterprises in the successful implementation of industrial applications . Among them, the low sulfated dynamic rare earth concentrate roasting technology to solve the Rare Earth Concentrate roasting exhaust and radioactive residue of environmental pollution problems. By the Beijing Nonferrous Metal Research Institute , Institute of Rare Earth New Material Joint Stock Company completed the " non- saponification extraction and separation of rare earth new technology " won 2012 State Science and Technology Invention since 2005 has worked in seven large rare earth the successful implementation of corporate , economic and environmental efficiency significantly. The aluminum salt of rare earth companies are using carbon -free ammonia separation and purification technology of rare earth oxides , 5,500 tons in Chongzuo construction / year rare earth separation plant. Beijing Nonferrous Metal Research Institute led the development of fuzzy / linkage extraction and separation processes , to meet the high demand for rare earth functional materials ultrapure rare earth oxides , as well as acid consumption can be reduced by more than 30 %. Domestic enterprises have been built using the technology 's first annual output of 100 tons of international ultrapure solvent extraction of rare earth oxide separation and purification of the production line .

China Nonferrous Engineering and Research Institute , said the former vice president Wang Guozhen , rare earth industry, environmental transformation is imminent. According to him, the existing domestic rare earth mining, smelting enterprises to achieve energy saving and radioactive pollutant discharge standards , it must be through technological innovation , the use of green production technology , reduce the " three wastes" and the radioactivity from the source waste generation , while reducing energy and material consumption . Promote the application of new technologies must be treated equally , focusing on large enterprises , such as Baotou, in color, in aluminum , Minmetals , etc., may lead the implementation of new technological innovation, there are no conditions to implement transformation either be eliminated or be integrated , which will also help resources enhance protection and technology , so as to promote industrial restructuring and upgrading of rare earth , in order to eliminate the expense of the environment disorderly competition .

Zhang Yin told reporters that China's rare earth resources, mining and separation of the production process to use a lot of acid and extractant pollution more links that can lead to destruction of vegetation resources , serious soil erosion . After monitoring, rare earth producers emissions, " three wastes" ammonia nitrogen , sulfur , fluorine , chlorine, and COD ( chemical oxygen demand ) generally exceeded, on the water and atmospheric pollution caused by varying degrees . Currently, part of the rare earth production technology and equipment , backward technology, environmental protection investment is still less pollution problems more prominent . Ganzhou only one place on the pollution caused by the production of rare earth ecological restoration will need to invest 38 billion yuan .

Inner Mongolia, Jiangxi, Sichuan and other places a number of rare earth enterprises to reporters reflect environmental technical innovation funding pressure brought to bear , in addition to technology transfer fee , the new production line using new technology also requires a large investment. They hope that the state and local governments to develop the technological transformation of enterprises preferential policies as soon as possible . Secretary-General of Chinese Society of Rare Earths Lin Dong Lu , deputy secretary general of China Rare Earth Industry Association, Wang iron and other experts suggested the NDRC and the Ministry of Finance can take advantage of the rare earth industry funds for technological upgrading , accelerate the promotion of independent technology ; while rare earth enterprises to "go out" accelerate advanced technology exchanges and cooperation with foreign enterprises to achieve win-win situation .
