The state-owned color metallurgy industry is currently showing such a pattern: On the one hand, it is actively eliminating backward production capacity, while on the other hand, output has been increasing rapidly. The unbalanced development of this kind of "sawboard" type not only has not reduced the energy consumption of China's non-ferrous metals industry, but has inflated instead. The momentum of rapid development from January to July this year shows that the entire industry is not optimistic about energy-saving and emission reduction. Energy consumption growth in output growth has also increased Since the beginning of this year, China’s non-ferrous metal industry has taken on the momentum of rapid growth in 2006 and continued to maintain rapid development. Production from January to July increased by 24.58% compared to the same period in 2006.
From January to July this year, China's total output of 10 non-ferrous metals reached 13.09 million tons, an increase of 2.58 million tons over the same period of 2006, an increase of 24.58%. Among them, 1.89 million tons of copper, an increase of 10.92%; original aluminum 6.94 million tons, an increase of 36.28%, an increase of 1.85 million tons over the same period in 2006, an increase of 72% of the total output of the industry's total production; lead 159 million tons, The year-on-year increase was 7.21%; zinc was 2.08 million tons, a year-on-year increase of 20.56%. It can be seen that the rapid growth of the production of electrolytic aluminum has become the main factor driving the growth of China's total output of non-ferrous metals.
China's non-ferrous metal industry during the "10th Five-Year Plan" energy-saving situation is: the main unit of energy consumption has declined. In 2005, the total AC power consumption of aluminum ingots dropped to 14575 kWh/ton, which was 5.8% lower than in 2000; the overall energy consumption of copper smelting was reduced to 733.1 kg standard coal/ton, which was 42.6% lower than in 2000; lead smelting integrated The energy consumption was reduced to 654.6 kg standard coal/ton, which was 9.2% lower than in 2000; the total energy consumption of electrolytic zinc was reduced to 1996.7kg standard coal/ton, which was 15.3% lower than in 2000; the total energy consumption of nickel smelting was 4056kg coal / Ton, down 10.9% from 2000. Despite the obvious energy-saving effect of the major non-ferrous metal products, the non-ferrous industry is still a big energy consumer in China. According to the information provided by China Nonferrous Metals Industry Association, China's non-ferrous metal industry consumed more than 80 million tons of standard coal annually in 2005, accounting for about 3.8% of domestic energy consumption and accounting for 6% of total domestic energy consumption. The rapid expansion of production capacity in the past two years, especially the increase in primary aluminum production, has led to a significant increase in energy consumption, which has brought tremendous pressure on China's non-ferrous industry to save energy and reduce emissions.
Non-ferrous industrial energy-saving emission reduction faced five difficulties analysis that China's non-ferrous metals industry, energy-saving emission reduction currently faces five difficulties: First, investment in smelting projects continue to increase. From January to July of this year, China's non-ferrous metal industry completed a fixed asset investment of 81.4 billion yuan, an increase of 41.33% over the same period of last year; this year, the newly-started project investment was 107.6 billion yuan, an increase of 67.33% over the same period of last year. From the perspective of investment structure, the percentage of non-ferrous metal mines that have completed investment continues to increase, and the investment in newly-started projects for smelting this year is relatively large, with a rapid growth rate. The reporter believes that the “larger, faster†smelting capacity not only fails to eliminate backward production capacity in accordance with the requirements of the national industrial policy, but also restores the production capacity that has been eliminated during the “10th Five-Year Plan†period. From the perspective of the increase in output, the production capacity Still expanding. From January to July of this year, it was initially estimated that China's non-ferrous metal industry enterprises above designated size achieved profits of 77.5 billion yuan, an increase of 63 percentage points from the same period of last year, and there has been a rare drop in recent years. The industry believes that the reduction of profits will inevitably affect the investment of enterprises in energy conservation and emission reduction, which undoubtedly worsens the industry's energy-saving and emission reduction work.
The second is the lack of industry energy consumption standards. Kang Yi, President of the China Non-Ferrous Metals Industry Association pointed out that due to the large number of non-ferrous metal products and complicated technology, China's existing energy consumption index system is not yet perfect. Some non-ferrous metal varieties do not have statistics on energy consumption indicators, and some metal types do not. It is difficult to accurately reflect the actual energy consumption by calculating the energy consumption index completely according to the (process) process. The analysis believes that the lack of industry standards makes China's non-ferrous metal energy consumption statistics lack of authority, science and accuracy, the industry's overall energy-saving emission reduction tasks can not be determined, the lack of a macro-control target system, coupled with the policy mechanism is not perfect, insufficient investment , it is difficult to achieve effective supervision. Therefore, in 2006 the specific situation of China's non-ferrous industry energy-saving emission reduction this year has not yet an authoritative and accurate data.
Third, the rapid growth of smelting production capacity has brought about an increase in the total energy consumption. In particular, the rapid growth of electrolytic aluminum production has brought shocks to the entire industry. Although China began to regulate the electrolytic aluminum industry from 2002, the growth rate of electrolytic aluminum production remains high. It is understood that in September 2005, China basically eliminated the backward self-baked aluminum electrolytic cell, and eliminated a total of 1.54 million tons of backward production capacity. However, after eliminating obsolete production capacity, the output of electrolytic aluminum in China has increased year after year. In 2005, 7.06 million tons of primary aluminum was produced. In 2006, 9.358 million tons of primary aluminum was produced, which was a year-on-year increase of 19.8%. From January to July this year, 6.69 million tons of primary aluminum was produced. The year-on-year increase of 1.85 million tons, a year-on-year increase of 36.28%, has become the main factor driving the growth of the total output of the industry. According to 2005, the lowest total electricity consumption of aluminum ingots was 14575 kWh/ton. This year, electrolytic aluminum alone increased electricity consumption by 2.696 billion kWh, resulting in a substantial increase in the total energy consumption of the industry.
Fourth, the mechanism for adjusting structural exit has not yet been established and it is difficult to effectively eliminate backward production capacity. According to reports, according to the national industrial policy and the forthcoming policy of energy consumption limit, China's non-ferrous metal industry currently has lagging small-scale pre-baked cell electrolytic aluminum production capacity of 650,000 tons, crude copper production capacity of about 500,000 tons, crude lead smelting The production equipment with capacity of about 1 million tons and zinc smelting capacity of about 900,000 tons needs to be renewed and eliminated. Kang Yi, president of the China Non-Ferrous Metals Industry Association, said that in the current situation where non-ferrous metals are at high prices, it is difficult to eliminate backward production capacity. In particular, the concentration of lead-zinc industry companies is low, SMEs are mostly, and many companies are located in relatively economic development. In backward areas, the elimination task is even more arduous.
Fifth, there is a lack of technological innovation capabilities, and technical support for energy saving and consumption reduction is weak. Although China's non-ferrous metal industry, energy-saving and energy-saving technology as the center of the transformation of energy consumption has declined, but overall, product unit consumption and the world's advanced level there is still a certain gap. In 2005, the integrated AC power consumption of China's electrolytic aluminum decreased to 14,575 kWh/ton, but compared with the international advanced level, there is still a gap of 475 kWh/ton, and there is a large gap between enterprises, and the best integrated electrolytic aluminum exchange in China Electricity consumption is 13,618 kWh/ton, while the worst company is 17,697 kWh/ton, a difference of more than 3,000 kWh/ton. In 2005, the total energy consumption of lead smelting in China was 0.65 tons of standard coal per ton, while the foreign advanced level was 0.3 tons of standard coal per ton. This is mainly due to the lack of technological innovation capability of enterprises. Some advanced technologies such as fully graphitized cathodes, carbonized silicon and silicon nitride composite lining materials, beneficiation Bayer process, lime Bayer process technology have not been widely used.
Major Measures for Energy-saving and Emission Reduction in Non-ferrous Industry On September 9th, the China Nonferrous Metals Industry Association, the National Development and Reform Commission, and the State Environmental Protection Administration held the National Conference on Non-ferrous Metals Industry Energy Conservation and Emission Reduction in Jinchang City, Gansu Province, China Nonferrous Metals Industry Association. It is expected that if no more effective measures are taken, China's non-ferrous metal production capacity during the “Eleventh Five-Year Plan†period will still maintain a high-speed growth trend, which poses a great pressure on the realization of energy-saving goals. At the meeting, the Nonferrous Metals Association proposed the main objectives of energy-saving and emission reduction of nonferrous metals industry during the “11th Five-Year Plan†period. By the end of 2010, the technical and economic indicators of the main non-ferrous metals products will approach or reach the world advanced level.
1. Adjust product structure and speed up the elimination of backward production capacity.
Continue to control the excessive growth of smelting capacity. The non-ferrous industry does a good job of controlling incremental, adjusting and optimizing the structure. Strict implementation of market access conditions, strict control of new smelting projects, continued use of adjusted export tax rebates, increase of export tariffs, reduction of export quotas, listing of some products in the category of processing trade prohibition, and increasing the implementation of “differential electricity prices†to control The smelting capacity has grown too fast.
Accelerating the elimination of outdated production capacity is the key to achieving success in energy conservation and emission reduction, and it is also a difficult point. In accordance with national industrial policies, we actively promoted the elimination of small prebaked electrolytic cells and backward blister copper, crude lead, and zinc smelting capacities that are not up to the standard for environmental protection.
2. Rely on advances in science and technology, actively promote the development and promotion of energy-saving emission reduction technologies.
Rely on scientific and technological progress and strengthen management to promote technological energy conservation, energy conversion and cascade utilization. It is necessary to improve the degree of intensification of the enterprise, adopt advanced technology and large-scale equipment, and improve the efficiency of energy use. Focused on the development of high-efficiency energy-saving technologies and equipment, self-heating of enhanced smelting and electrolysis processes, equipment and automatic control technologies, hydrometallurgical energy-saving technologies, electrolytic aluminum liquids for direct and continuous preparation of alloy cast billets, cast slabs, non-ferrous metal processing energy-saving technologies Etc.; to strengthen the furnace insulation, improve the combustion method and atmosphere, improve thermal efficiency; to information technology as the core, energy-saving technology optimization and integration, the energy efficiency of the production process is always controlled in the best condition; to optimize the raw material structure, improve the fine material Ratio, save energy.
In non-ferrous metal processing, we must focus on the continuous process and automation of the processing process, shorten the technological process, and achieve the goals of energy conservation, material saving, and environmental protection.
3. Increase investment and actively promote key projects.
According to the "Energy Conservation and Emission Reduction Work Program for Non-ferrous Metals Industry," the Nonferrous Metals Association recommends mines for safe and efficient mining and disaster prevention, non-waste mining of metal deposits and environmental remediation, a new flotation process for hard aluminum bauxite and bauxite, and utilization of low grade copper deposits. There are 18 key projects such as technology, continuous intensification of smelting, blowing of new short-process copper, and tailings, red mud, slag, and electrolytic tank-lined solid waste recycling technology as important measures to promote energy conservation and emission reduction.
4. Innovative mode to accelerate the development of circular economy.
To develop the recycling economy of the non-ferrous metal industry, we must focus on every aspect of mining, selection, smelting and processing, and do everything possible to increase the utilization rate of resources; we must strengthen the comprehensive development and utilization of resources and increase the comprehensive utilization of the associated associated mineral resources; we must vigorously carry out harmful smoke. , mining waste rock, ore tailings, smelting waste residue utilization; to strengthen the recycling of scrap metal, improve the level of recycled metal utilization. We must vigorously develop imported renewable resource processing parks and recycled metal resource utilization industries. All enterprises must proceed from reality, strengthen the comprehensive utilization of resources, and accelerate the development of circular economy.
5. Establish and improve the industry energy conservation and emission reduction index system and assessment system.
Due to the large number of non-ferrous metal products and complicated process, the existing energy consumption index system is not yet perfect, and some metal varieties do not have the statistics of energy consumption indicators; some metal varieties do not fully calculate energy consumption indicators according to the (process) process production process. It is difficult to accurately reflect the actual energy consumption. In this regard, it is necessary to combine the formulation of non-ferrous metal energy consumption quota standards, refer to the internationally accepted statistical principles, and combine China's reality to continuously improve energy conservation.
From January to July this year, China's total output of 10 non-ferrous metals reached 13.09 million tons, an increase of 2.58 million tons over the same period of 2006, an increase of 24.58%. Among them, 1.89 million tons of copper, an increase of 10.92%; original aluminum 6.94 million tons, an increase of 36.28%, an increase of 1.85 million tons over the same period in 2006, an increase of 72% of the total output of the industry's total production; lead 159 million tons, The year-on-year increase was 7.21%; zinc was 2.08 million tons, a year-on-year increase of 20.56%. It can be seen that the rapid growth of the production of electrolytic aluminum has become the main factor driving the growth of China's total output of non-ferrous metals.
China's non-ferrous metal industry during the "10th Five-Year Plan" energy-saving situation is: the main unit of energy consumption has declined.

Despite the obvious energy-saving effect of the major non-ferrous metal products, the non-ferrous industry is still a big energy consumer in China. According to the information provided by China Nonferrous Metals Industry Association, China's non-ferrous metal industry consumed more than 80 million tons of standard coal annually in 2005, accounting for about 3.8% of domestic energy consumption and accounting for 6% of total domestic energy consumption.
