Recycling of scrap copper

China as the largest developing country in the world, in realizing industrialized process especially in keeping Tao Min economy in the process of rapid development of non-ferrous metals demand is very, especially copper its supply is very tight. Copper shortage is to restrict our country copper processing industry is one of the main factors. The 2011 world copper output is 20000000 t about, among them 85% to 90% from the copper extraction and smelting out 10% ~ 15% from Cu recycling. So the copper recycling industry becom the important way for copper resources shortage.In view of present situation of copper scrap copper resources and Renewable investment, low energy consumption and cost, little pollution and has simple process and other characteristics, copper scrap recycling in China by mushroom considered.

1 Chinese copper demand and resource status

1.1 Chinese copper demand

At present, China has become the world's largest consumer of copper, copper processing industry manufacturing base and the copper base product export country. Our country is in the world of refined copper consumption growth is the rapiddest, the average growth rate is2.4 times of world, especially since 2000, an average annual increase of about300000 t, become pull move consumption growth in the major countries of world copper. Copper are mainly used for electric power, electrical and electronics, machinery manufacturing, construction, transportation and other industries. With the rapid development of automobile industry, the state of rural electrified wire netting transform, especially copper shortage. In 2010December the national development and Reform Commission report, in construction, automotive and other industries to speed the development of drive, China copper consumption showed a steady upward trend, demand growth is much higher than the growth rate of the Chinese alligator.

1.2 of China's copper resources

Copper resources shortage is China's copper industry the most outstanding problem, industry of our country copper smelting capacity greatly exceeds the guarantee ability of copper concentrate. China's copper base reserves30420000 resources, resources total 62180000t. Copper mine reserves and foreign comparable part, not exceeding 18000000 t12J, ranking seventh in the world. But from tell on the whole, the copper resources in China is still very poor ( Especially the lack of rich copper ), and foreign copper resource countries still have quite big difference. China's domestic copper concentrate supply is less than 30%, more than 70% of the need to rely on imports.

Copper resources in China is characterized by small deposits, large, superlarge deposit less. The characteristics of the hill of our country copper mine construction
