Demanding central enterprises to play a leading role
The above “Proposal†proposes to accelerate the industrial application and promotion of low-carbon, low-salt and non-ammonia-nitrogen rare earth oxide separation and purification technology by 2017, complete the industrial application demonstration of rare earth concentrate low-temperature sulphation dynamic roasting technology, and realize rare earth smelting separation. The use of acid and alkali in the process is reduced, and the comprehensive utilization efficiency of resources is improved.
The "Proposal" pointed out that the promotion of non-saponification extraction and separation of rare earth technology, fuzzy linkage extraction separation process, and strive to achieve non-saponification extraction and separation of rare earth technology in 2017 to reach 50%, fuzzy linkage extraction separation process penetration rate of 85%. By promoting the above technologies, it can save hydrochloric acid (30%) 120,000 tons/year, sodium hydroxide (30%) 373,000 tons/year or liquid ammonia 50,000 tons/year, and ammonia nitrogen in wastewater can be reduced by 53,000 tons/year.
The above-mentioned "Notice" pointed out that relevant local industrial authorities should take the promotion of clean production technology in the rare earth industry as an important measure to promote energy conservation and emission reduction, increase efforts and accelerate the implementation of organizational plans. Strengthen investigation and research, and combine the implementation of clean production technology in the region to promote the status quo and implementation potential, and develop targeted clean production technology implementation plans. The clean production technology specified in the plan is listed as the key point of financial guidance and financial support such as energy conservation and emission reduction, technological transformation, clean production, and circular economy. Increase publicity and training, strengthen relevant information exchange, and guide enterprises to apply clean production technology.
In addition, the Ministry of Industry and Information Technology said that the relevant rare earth enterprises, as the main application of clean production technology, should implement the clean production technology transformation as a fundamental way to improve the technological level and core competitiveness of enterprises, prevent and reduce pollutants from the source, and achieve clean development. The central enterprise group should actively support the clean production technology in the application promotion plan of its affiliated enterprises, and prioritize the relevant demonstration and promotion projects into the group project implementation plan and provide financial support.
Chinalco said it will implement as required
Judging from the technology proposed by the “Programâ€, these technologies have been successfully industrialized in Jiangsu Guosheng Rare Earth Company, Baoding Rare Earth Material Testing Plant, Rare Earth New Materials Co., Ltd. and Guangdong Zhujiang Rare Earth Company. application. The “Non-saponification extraction and separation of rare earth new technology†developed by Beijing Nonferrous Metals Research Institute and Rare Earth New Materials Co., Ltd. won the second prize of National Science and Technology Invention in 2012, and has been successfully implemented in 7 large rare earth enterprises. . Chinalco Rare Earth Company is currently using the low-carbon low-salt and ammonia-free nitrogen rare earth oxide separation and purification technology in the 5,500 ton/year rare earth separation plant in Chongzuo, Guangxi.
However, according to the reporter's understanding, before the "Notice" for comments, many responsible persons of rare earth enterprises in Inner Mongolia, Jiangxi, Sichuan and other places reported that the financial pressure brought by environmental protection technology reform is unbearable, in addition to technology transfer fees, adopt new New technology production lines also require large investments. They hope that the state and local governments will formulate preferential policies for technological transformation enterprises as soon as possible.
In this regard, yesterday, China Aluminum said to the "Securities Daily" reporter that it will be implemented in accordance with the requirements of the Ministry of Industry and Information Technology. As for the above-mentioned rare earth separation project carried out by Chongzuo in Guangxi, some people told reporters that the project is still in progress. In the process of advancement.
In the "Notice" for comments, Lin Donglu, secretary general of the China Rare Earth Society, and Wang Xiaotie, deputy secretary general of the China Rare Earth Industry Association, suggested that the National Development and Reform Commission and the Ministry of Finance's rare earth industry technical reform special funds could be used to accelerate the promotion of independent technology; Rare earth enterprises should "go out" and accelerate exchanges and cooperation with foreign companies with advanced technology to achieve mutual benefit and win-win results.
