Upgrade Plan (hereinafter referred to as “Programâ€), the implementation period is from 2010 to 2011.

Optimize and upgrade to improve resource control The relevant personnel of the Raw Materials Division of the Ministry of Industry and Information Technology, who participated in the program, said that the central region is an important non-ferrous metal mining, smelting and processing base in China. Due to the rich mineral resources and good industrial base, after years of development, the non-ferrous industry has become a pillar industry in the central region. However, due to years of extensive development, some deep-seated contradictions and problems have also accumulated, and the level of local resource protection is getting lower and lower. For example, the average size of rare earth smelting enterprises in Jiangxi is less than 2,000 tons, and more than 90% of Anhui copper concentrates are imported. The reserves of Henan bauxite can only maintain the normal production needs of enterprises for 6-7 years.
According to reports, the "Program" must first consolidate the existing advantages of the raw materials industry in the central region, and further adjust and optimize the industrial organization structure, product structure, technical process equipment structure and regional industrial layout. The "Plan" clearly pointed out that it is necessary to build aluminum industrial bases such as Chinalco, Luneng Jinbei and Xin'an, develop Jiangtong, Tongling and Daye non-ferrous copper industrial bases, optimize Henan and Hunan lead and zinc production and processing bases, and southern and southern Hunan. Construction of rare metal bases such as rare earths.
In addition, accelerating the merger and reorganization of non-ferrous enterprises has always been the focus of the outside world. The "Proposal" requires accelerating the integration of non-ferrous metal minerals, smelting and processing resources within and outside the region, and giving full play to the integration of large-scale enterprise groups such as Chinalco, Minmetals, Jiangxi Copper, Tongling Nonferrous, Hunan Nonferrous, Yuguang Gold and Lead, Daye Nonferrous. The leading role of the non-ferrous metal industry in the central region, focusing on cultivating 1 or 2 non-ferrous metal enterprises and large-scale enterprise groups with international competitiveness, 5-8 domestic leading enterprises.
At the same time, we must improve resource control and increase industrial concentration. Encourage the "coal, electricity, aluminum" enterprises to reunite and reorganize to achieve integrated development. Vigorously promote the intensive development of industries such as magnesium, tungsten, tin, antimony, molybdenum, rare earth and gold, support horizontal mergers and acquisitions of key backbone enterprises, and achieve efficient use of resources.
Development of deep processing and extension of industrial chain Zhao Bo, deputy director of the Ministry of Copper, China Nonferrous Metals Industry Association, said that the output of ten non-ferrous metals in China last year was 26,084,800 tons, of which 10 kinds of non-ferrous metals produced in the central region were Henan, Hunan, Anhui, Four provinces in Shanxi. If you add Jiangxi and Hubei provinces, the production of ten non-ferrous metals in the central region will account for half of the country's total output. However, many resource advantages in the central region have not yet become economic advantages, and it is necessary to continuously optimize and upgrade the production of high-tech products and extend the industrial chain.
Taking tungsten as an example, the low-end raw materials of tungsten industry are currently exported in large quantities. Industrial products are mainly low-end tools, drill bits and wear-resistant parts, and high-end products mainly rely on imports. Zhang Hongguo, deputy secretary-general of the China Nonferrous Metals Industry Association, said that these resources are becoming less and less. If protection is not developed early, there will be no resources available in the future. Although China's tungsten reserves and production rank first in the world, the development of China's cemented carbide technology is mainly based on tracking imitation and introduction, and does not transform resource advantages into economic advantages.
Therefore, the "Proposal" proposes to do a good job, adjust and optimize the product structure, and require the non-ferrous metal industry to focus on the development of high-precision high-performance sheet and strip, foil and other intensive processing products, vigorously develop alloy products and new materials, and accelerate the industry. The high-end link of the chain is transferred. At the same time, rationally control the development scale of rare metals and improve the deep processing capability. Accelerate the construction of a comprehensive recycling and utilization system for non-ferrous metals covering the whole society and develop a renewable non-ferrous metal industry.
The central region is also quite rich in the advantageous resources closely related to the development of high technology. Such as rare earth, titanium, magnesium, tungsten, molybdenum, gallium, indium, antimony, antimony, etc., but most of them can only be processed into primary mineral products or primary smelting products, so optimizing product structure is imperative. The proportion of metal and non-metal deep-processing products and fine chemical products with high technical content and high added value is further improved in the “Proposalâ€, providing new materials for high-tech industries such as new energy, electronic information, equipment, aerospace, defense and military industries. .
Breaking through the bottleneck of energy-saving and environmental protection technology Due to the long production chain and complicated process in mining, smelting and processing, the non-ferrous metal industry has become a key industry for energy saving and emission reduction in China in recent years. One of its technical reform goals is to break through the relevant technical bottlenecks of energy conservation and environmental protection. .
Smelting is an important part of the energy consumption of non-ferrous metal industry production, and the energy consumption of aluminum smelting is the largest. At present, the DC power consumption per ton of aluminum electrolysis is between 13,000 and 13,300 kWh, and the electricity consumed by electrolytic aluminum accounts for about 5% of the national electricity consumption. The "Proposal" requires targeted adjustments to the existing electrolytic aluminum process, so that the current DC consumption of tons of aluminum is less than 12,000 kWh. At the same time, we must vigorously develop copper, lead and zinc smelting short process technology, flue gas desulfurization, high performance special copper and aluminum production process, ton aluminum direct current consumption of less than 12,500 kWh of electrolytic aluminum key process, low grade and difficult selection of smelting and efficient use of minerals , tailings and red mud comprehensive utilization, regeneration metal retention performance and other technologies.
Zhao Bo told reporters that the technological transformation of copper smelting will speed up the elimination of the backward copper smelting process, such as closed blast furnace, reverberatory furnace and electric furnace, so that the flue gas can be fully utilized, and the comprehensive utilization rate of sulfur is over 95%.
The "Proposal" requires that the aluminum electrolysis tanks of 160kA and below should be phased out, and the "small non-ferrous" enterprises such as lead-zinc smelters with an annual output of less than 50,000 tons and metal magnesium with an annual output of less than 10,000 tons should be eliminated within a time limit. The "Proposal" requires that the backward production capacity of backward technological production, poor product quality, high safety risks, high energy and resource consumption, and serious environmental pollution should be accelerated. Key enterprises and regions should phase out reverberatory furnaces and blast furnaces, electric furnace copper smelting capacity, sintering pot smelting capacity, backward zinc smelting capacity and backward small pre-baked electrolytic aluminum production capacity, and gradually phase out lead smelting capacity of backward sintering machines.
In addition, we must accelerate the pace of technological progress. The "Proposal" requires efforts to achieve new breakthroughs in key process technologies, energy-saving and emission reduction technologies, as well as high-end product development, production and application technologies.
