Non-ferrous metals industry is a high energy consumption of the resource-based industries, how to minimal mineral resources, energy consumption, the greatest economic and social benefits, which is the non-ferrous metal industry the key issues of sustainable development. Recently, the National Development and Reform Commission, the State Environmental Protection Administration and other relevant departments and provincial governments, in the nation’s key industries and key areas has embarked on a circular economy pilot. Non-ferrous metals, as one of the key industries, there are 12 enterprises were included in the first batch of pilot units, which is the promotion of economic growth mode transformation, development of circular economy and building a conservation-oriented industries, and promote the sustainable development of China’s nonferrous metals industry of great importance .
the transformation of economic growth mode
non-ferrous metals industry is the important foundation of China’s national economy, raw materials industries, business processes determine the characteristics of non-ferrous metals industry is the most qualified, most potential to develop recycling economy industries. The reporter learned from recently held in Nanchang, China’s nonferrous metal industry, striving for conservation-oriented enterprises meeting was informed that, in recent years, China’s nonferrous metals industry has been rapid development, has become the world’s major non-ferrous metals producer. Aluminum’s fastest-growing, technological progress, and most obvious. So far, China has basically eliminated the backward self-baking electrolytic cell, the unit to reduce energy consumption, the environment greatly improved, now more than 80% capacity with 160 more than a thousand large-scale pre-baked slot; with independent intellectual property rights 320 1000-an large-scale pre-baked anode technology has been exported to India, Kazakhstan, Iran and other countries; 350 1000 China’s own development of an already large-scale pre-baked anode and Shenhuo Qingtongxia Aluminum Group, the normal production, as the world’s largest production capacity of the current series of slots . Copper, lead, zinc, nickel smelting technology has achieved much progress. Copper, aluminum processing technology and equipment level has been greatly improved, and some high-precision products have been exported to foreign countries has changed the situation heavily dependent on imports. The relevant statistics show that in 2005 the first 10 months, China’s nonferrous metals industry (excluding independent gold enterprises) in fixed assets investment 63.96 billion yuan over the same period in 2004 increased 35.9%, an increase higher than the national average of 8.36 percentage points. In recent years, rapid development of non-state-owned enterprises now account for half of non-ferrous metals industries. Diverse sources of capital investment for the non-ferrous metals industry increased capacity for sustained development. Meanwhile, the advantages of state-owned large enterprises with their own funds continue to accumulate and direct financing capabilities, capacity for sustainable development has accelerated noticeably.
However, the rapid development of China’s nonferrous metals industry, there are still some outstanding contradictions and constraints generally in line with the international advanced level there are still large gaps, especially in facing the development of resources, energy and the environment, critical challenges and continue to rely on high input, high consumption, high emission and low efficiency of the extensive mode of growth is indeed unsustainable, therefore, need to further change the mode of growth and building a conservation-oriented industries, and taking a new road of industrialization.
At present, non-ferrous mineral resources, comprehensive utilization rate of about 60% lower than in developed countries 10 to 15 percentage points. Among them, a total, comprehensive utilization rate of associated ore only 40%, 20 percentage points lower than in developed countries; lead, zinc, tungsten, molybdenum and other metal ore-dressing recovery, copper, nickel smelting total recovery with foreign advanced level still a gap. In addition, China’s major copper and aluminum businesses of copper, aluminum integrated yield levels were low compared with foreign advanced 10 and 5 percentage points, only the China’s annual consumption of more than copper, aluminum several hundred thousand tons.
low utilization rate of China’s non-ferrous metals recycling. United States, Germany, France and Japan accounted for its aluminum recycling aluminum volume are as follows: 58%, 62%, 98% and 64%, while China is only about 20% recycled aluminum. To improve the use of recycled metal, not only can reduce the direct consumption of mineral resources, but also reduce the large number of emissions, waste emissions, can receive better economic and social benefits.
At present, China’s imperial smelting furnace smelting of the average unit energy consumption higher than the international advanced level of 33.4%, the average energy consumption of lead smelting higher than the international advanced level of 84.2%, the average energy consumption of zinc hydrometallurgy higher than the international advanced level in nearly 40% Even an advanced copper flash smelting unit product energy consumption lower than the international average, up 0.1 tons of standard coal consumption of electrolytic aluminum production of direct current has reached the international advanced level on average, but the comprehensive energy consumption indicators still a gap.
authorities believe that China’s nonferrous metals industry vigorously develop circular economy is taking a new road to industrialization, the only way to achieve sustainable development and building a conservation-oriented industries, the task remains very difficult.
vigorously promote energy conservation
In recent years, the development of China’s nonferrous metals industry, not only growing faster, but also in improving the growth quality and efficiency is also the best period. 12 have been listed as a national circular economy pilot colored companies in the “bigger and stronger, more competitive,” out of ideas on the development of a high technological content, good economic returns, low resources consumption, little environmental pollution, human resources full play to the new road to industrialization. It is understood that some businesses in this area has been pre-empted -
Jiangxi Copper Company to vigorously develop circular economy, technology innovation and system innovation as a driving force in the comprehensive utilization of resources has made remarkable achievements. For “waste gas, waste water, waste residue,” the establishment of eco-industrial chain, the successful recovery of sulfur dioxide from the exhaust gas, tailings to be comprehensive utilization; wastewater used for the election sulfur, copper election process, so that resource.
Jinchuan’s nickel mine is a large multi-metal symbiotic sulfide copper-nickel mine, because of its unique resources and conditions, as early as age 70 in the last century was listed as a national comprehensive utilization of mineral resources three bases. Following the company’s 15 years of major scientific and technological research, at present, have achieved significant results. In recent years, the Jinchuan Company to scientific and technological progress and technical innovation as the breakthrough point to comprehensive utilization of resources as the center, to conduct joint science and technology research with some of the cutting-edge technologies for the production, so that technical and economic indicators and the comprehensive utilization levels have been greatly improved, in order to Jinchuan’s a strong guarantee for sustainable development.
Jinduicheng Molybdenum Group Co., Ltd. is the world’s third-largest Jicai, election, smelting, science, industry and trade in one of the large modern joint ventures. In the long-term production and management development, Jinduicheng Molybdenum Group Co., Ltd. from the enterprise reality, committed to protecting the conservation of resources, adjusting product structure and the protection of ecological environment, out of a development of circular economy and build environment-friendly city of New Mo way. Now, Jinduicheng Molybdenum Group Co., Ltd. dressing wastewater discharge passing rate remained at 98% of industrial soot emissions from full compliance.
Tongling Nonferrous Metals Group in the development of circular economy model to explore the positive aspects of proposed mining, smelting, processing, and chemical 4 cycles economic circle of planning and economic evaluation index system, and conducted to quantify. Yuguang Gold & Lead and Jiangsu Chun Hing Group successfully do a good job of lead recycling smelting work for the lead recycling industry, provide a reference. Yunnan Aluminum, Zhuzhou Smelter, and many other units in the energy saving, environmental protection, create a conservation-oriented enterprises have achieved good results.
can be said that non-ferrous metals industrial enterprises in the development of circular economy has taken a substantial step, and have achieved fruitful results. With the large state-owned enterprises continue to accumulate their own funds and direct financing capabilities, capacity for sustainable development of China’s nonferrous metals industry will be more and more stronger.
循环经济连衣裙中国有色金属
非有色金属工业是高耗能资源型产业,如何{zd1}限度的矿产资源,能源消耗,{zd0}的经济效益和社会效益,这是有色金属工业可持续发展的关键问题。最近,国家发展和改革委员会,国家环境保护总局等有关部门和省级政府,在全国重点行业和重点地区开展了循环经济试点。有色金属,作为重点产业之一,有12个企业的试点单位,这是转变经济增长方式,发展循环经济,建设节约列入首批推广型产业,促进在中国的有色金属工业具有重要意义的可持续发展。
经济增长方式的转变
非有色金属工业是中国国民经济的重要基础原材料工业,业务流程确定非特点,有色金属工业是最有资格,最有潜力,发展循环经济产业。记者从近日召开的保护而努力,南昌,中国的有色金属工业,外向型企业会议上获悉获悉,近年来,中国有色金属工业得到了快速发展,已成为世界主要的非铁金属生产商。铝的增长速度最快,技术进步,最明显的。到目前为止,中国已基本淘汰落后自焙电解槽,该单位以减少能源消耗,环境大大改善,现已超过80 160%的容量超过1000大型预焙槽,具有自主知识产权产权320千安大型预焙槽技术已出口到印度,哈萨克斯坦,伊朗和其他国家; 350 1000中国自身发展的一个已经大规模的预焙槽和神火青铜峡铝业集团,正常生产,作为世界上{zd0}的当前一系列的时段生产能力。铜,铅,锌,镍冶炼技术取得了很大进展。铜,铝的加工技术和装备水平有了很大提高,一些高精度的产品已出口到国外,改变了局势的严重依赖进口。有关统计资料显示,2005年前10个月,中国有色金属工业(不包括固定资产投资六三九六〇 〇 〇 〇 〇 〇 〇比2004年同期的人民币独立黄金企业)增加35.9%,增幅高于全国8.36个百分点,平均。近年来,迅速发展的非国有企业现在的非占一半,有色金属等行业。资金来源多元化投资的非有色金属工业持续发展的增长能力。同时,国有优势的国有自己的资金大企业不断积累和直接融资能力,可持续发展能力明显加快。
不过,中国有色金属工业的快速发展,还存在一些突出矛盾和制约因素大致符合国际先进水平尚有较大差距,特别是在面临资源,能源和环境,发展的严峻挑战,并继续依靠高投入,高消耗,高排放和增长方式粗放的低效率实在是不可持续的,因此,必须进一步转变增长方式,建设节约型产业,走新型道路工业化。
目前,有色金属矿产资源,约60%,比发达国家10至15个百分点,综合利用率低。其中,总,相关的矿石综合利用率只有40%,20个百分点,低于发达国家,铅,锌,钨,钼等金属矿选矿回收率,铜,镍冶炼技术与国外先进水平xx恢复仍有差距。此外,中国主要的铜和铝的铜企业,铝综合产量水平比较低,与国外先进的10和5个百分点,只有中国的多铜,铝,几十万吨的消费量。
对中国的非利用率低,回收有色金属。美国,德国,法国,日本占了金属铝的再生铝量如下:58%,62%,98%和64%,而中国只有约20%的再生铝。为了提高再生金属的使用,不仅可以减少矿产资源的直接消费,而且也减少了大量排放,废物排放,能得到较好的经济效益和社会效益。
目前,中国的密闭鼓风炉的平均单位能耗较高的冶炼比国际的33.4%,铅冶炼比国际的84.2%,锌湿法冶炼的平均能耗先进水平较高的平均能耗先进水平比国际近40%,即使是先进的先进水平较高的铜闪速熔炼单位产品能耗低于国际平均水平,同比增长0.1直流已达到国际先进水平平均,但电解铝生产消费吨标准煤在综合能耗指标仍有差距。
当局认为,中国有色金属工业,大力发展循环经济是走新型工业化道路的{wy}途径实现可持续发展,建设资源节约型产业,任务仍然十分艰巨。
大力提倡节约能源
近年来
,是中国有色金属工业的发展,不仅增长快,而且在提高增长的质量和效率,也是{zh0}的时期。 12个被列为国家循环经济色彩的“做大做强,更有竞争力的公司的试点,”走出思想的一个发展技术含量高,经济效益好,资源消耗低,环境污染少,人力资源优势得到充分发挥的新型工业化道路。据了解,在这方面的一些企业已预设-
