China's non-ferrous metal resources inadequate protection prominent problem 日期:[2013-02-02]

China's nonferrous metal resource guarantee shortage problems

     China nonferrous metals industry association, vice chairman of ShangFuShan yesterday in the national nonferrous metal sparetime university conference that, in recent years, China's domestic important nonferrous metal mineral achieve positive results, but no significant breakthroughWith the mining strength increase, reserve-production ratio downward trend increasingly obvious.

According to the institute of nonferrous association analysis, in bulk mineral, in 2010 the domestic copper reserve-production ratio is 9.5, rather than 29.8 in 2003 dropped by 20.3; Bauxite reserve-production ratio is 16.9, 32.8 in 2003 than down 15.9. ShangFuShan said, reserve-production ratio of fell sharply, make our country large non-ferrous metal mineral raw materials ratio of dependence on foreign continues to rise.

 He says, the current and purchase a period, our country is still in promoting the industrialization, the urbanization, informationization, internationalization and market phase, and non-ferrous metals demand will continue to grow, and find out the domestic existing reserves far cannot satisfy the need. Therefore, increasing mining investment and improve the yield of minerals, especially improve the copper, aluminum, lead, zinc and other large sums of minerals output, basic won't exist the problem of excess market.

Colored association statistics show that in 2011, China's copper, lead, zinc, nickel, tin and antimony and so on six kinds of non-ferrous metal ore concentrate metal production 8.25 million tons, up 18.0%, far higher than the "11th five-year plan" period with an average annual growth rate of 9.3%. With a batch of new mine and put into production, is expected in the next few years China's major non-ferrous metal products production will continue to maintain rapid growth.

Experts forecast that China's economic and social development of mineral resources, the high demand will still last for a period of time, many important energy and mineral raw material still have 10 years - 20 years of peak demand, the resource demand is expected to peak around 2025 coming. "Next, enterprises should take an active part in national prospecting breakthrough strategic action, take practical action to promote resource exploration made great breakthrough. At the same time, to accelerate the technological progress, increase the comprehensive utilization of resources efforts, and strive to develop green mining, development, and to promote the city mining resources economical utilization and comprehensive utilization. The state council advisors, China nonferrous metals industry association ChenQuanXun said

ShangFuShan has said, to accelerate the technological progress, and strive to made breakthroughs in key technologies. He said, now need to breakthrough technology mainly includes: mineral resources exploration common key technology; Large metal deposit underground enhanced recovery key technology and equipment; Complex low grade sulphide ore resources of biological leaching technology; Nonferrous metal mineral harmful element harmless treatment and resource utilization of resources comprehensive utilization technology, etc.

He also pointed out that, at present, the development of green mining, the construction of green mining is non-ferrous metal mining development an important task. Especially in the next period, China's non-ferrous metal resources continuous base is located in the most ecological environment bearing capacity is weak and ecological function, the green mine construction is particularly important.
