People often put those areas that are rich in precious metal electronic products compared to "urban mining". In the increasingly scarce resources, advocate recycling economy is more and more today, the recycling of metals also gradually become a huge industry.
With copper resources, according to the China nonferrous metals industry association renewable metal branch vice President and secretary general introduction, in 2014, the recovery of copper production is around 3 million tons. In the past five years ago, China a total of 50 cities mining projects is established. "Recycling copper resources meaning is very important for us. Because China is already the world's largest manufacturer of mechanical and electronic products and household appliances production country, a lot of infrastructure is under construction at the same time, all of these need a lot of copper and copper products."
In copper recycling industry, wire and cable recovery is one important part of, because the proportion of copper in wire and cable used is very large, more than 60%.
Adhere to the sustainable corporation circulation industry has great potential/holds great promise
Rich "urban mining" also attracted some private companies in this field. Can a few days ago, the tianjin new group (hereinafter referred to as the "new") found that strongly support circulation industry in the country of good policies, many resources regeneration enterprises engaged in a variety of content began to grow, and among them, deep processing of copper scrap is one of the important business of the enterprise.
It is understood that the new can be used as a small park in micro enterprises, since 1996 in secondary copper industry, in 2008, the new will expand into real secondary copper smelting project.
According to introducing, the development of secondary copper rod in the home also is still in its early stage. At present, the new can make renewable raw materials of the copper rod in more than 90% copper scrap imported from abroad, using the domestic copper scrap ratio is relatively small. In recent years, the regeneration of the copper rod quality problem has also been mentioned. Domestic large and small secondary copper rod, technical level is not the same, produce renewable copper rod quality also have difference. New can group vice President, said the adoption of Italy's lopez and Spain rafael company joint development of miscellaneous scrap copper fire refining process, the new can produce recycled copper rod, both in terms of elongation, twisted, resistivity, and oxygen content of these indicators, can meet the national standards.
From "the contention of copper aluminum" in the field of regenerative
In recent years, the cable industry in "the contention of copper aluminum" voice. And one of the view that a shortage of copper resources in China, and aluminum resources are relatively less nervous. But if from the point of view of resources recycling, is not at all. First of all, the performance of copper itself determines its can be recycled one hundred percent. China's copper production, renewable copper accounted for about 40%. In the aluminum production in our country, recycled aluminum accounted for only about 20%. For power cable industry, renewable copper using proportion about 50%, and using basic aluminium is 0.
Before making a secondary copper rod, he has more than 20 years of experience as a secondary aluminum. "We are in the market of rare earth aluminum alloy cable can't be recycled aluminum production. The primary aluminum large quantities of electrical energy, so it can't save a lot of cost. Said aluminum alloy is economic, and have the renewable resource point of view."
In addition, the expert thinks, although at present domestic copper supply, but was able to get enough from the international copper to meet the needs of national economic development. Demand and copper will not endless growth, the development of abroad has proved that as the economic development to a certain extent, people demand for copper resources also reached its peak.
Secondary copper industry will be rapid development
It is reported that the proportion of secondary copper rod is not big, secondary copper pole the current annual production is between 200000 ~ 300000 tons, but the industry's future development prospect of inestimable. In Europe, the UK, France, Germany and other developed countries the use of renewable copper are more than 40%, particularly in Italy reached almost 100%. "The industry has a more rapid growth in the future. Because if you compare the performance of regeneration and native copper, according to the current technology to produce the electrician copper rod and its physical properties with native copper don't have too big difference, the only short of indicators, is on the content of impurities. Secondary copper than native copper content of impurities, but if it is used first melting into the anode plate again, by means of electrochemical regeneration of copper impurity content can be reduced to the standard of native copper, just the cost of doing so is too high. And this factor does not affect the use of electric pole material. Now with the development of the whole national economy, the use of renewable materials has been referred to the agenda of the country, the amount of secondary copper rod will be more and more, will be the highlight of a use." Experts on regeneration of the copper rod is full of confidence in the future.
