copper concentrate

Quality requirements for cathode copper: copper concentrate is produced by electrolytic refining or electrolytic deposition.

Use of electrolytic copper

CATHODE COPPER is a non-ferrous metal closely related to human beings. It is widely used in electric, light industry, machinery manufacturing, construction industry, national defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in China.

copper smelting enterprises is widely used and consumed in the electrical and electronic industries, accounting for more than half of the total consumption.Used for all kinds of cables and wires, motors and transformers winding resistance, switches and printed circuit boards.

Used in the manufacture of industrial valves and fittings, instruments, plain bearings, moulds, heat exchangers and pumps, etc.

Widely used in the chemical industry in the manufacture of vacuum equipment, distillation pot, brewing pot.

In the defense industry for the manufacture of bullets, shells, gun parts, etc., each production of a million bullets, the need for copper 13-14 tons.

In the construction industry, used as a variety of pipes, pipe accessories, decorative devices.

Prospects for development

After issuing a series of regulations to rectify the steel industry, the NDRC began to crack down on the copper smelting industry.On Friday, the national development and reform commission (NDRC) released the "access conditions for copper smelting industry," which includes specific provisions on investment conditions, technology and equipment, energy consumption and environmental protection to regulate investment in the copper smelting industry and stop blind investment and low-level repetitive construction.Spurred by high CATHODE COPPER price, a new wave of expansion in copper smelting capacity is under way in China.In addition to the industry leading enterprises, some have never done copper smelting enterprises have also set foot in the meantime, in the electrolytic aluminum industry blind investment heat seems to appear in the field of copper smelting.Some in the industry worry that if left unchecked, China's copper smelters will soon follow the lead of the aluminium industry as a whole.Jiangxi copper (group), the first major copper producer in China, is reported by China business news.A company in fujian is preparing to build a 400,000-ton copper smelting line.Copper smelting projects under construction and in preparation have a capacity of 2.38m tonnes, equivalent to existing capacity in China.Copper smelting industry access conditions, the most notable is the qualification for copper smelting enterprises made clear rules, regulations must accord with its own metallurgical raw material ratio of 25% or more (or joint venture cooperation has its own mining raw materials and by five years of long-term contract mining raw materials to achieve more than 40% of the total demand), project capital ratio of 35% and above conditions.

The production process of copper in China is dominated by copper concentrate and metallurgical process.However, the current situation is that the processing capacity is greater than the smelting capacity, and the smelting capacity is much more than the guarantee capacity of copper concentrate, copper concentrate resources and waste copper are imported.Statistics show that since the 21st century, the domestic production of copper concentrate has not increased significantly, maintained at the annual output of 600 thousand tons (copper content, the same below), the end of 2007 will form nearly 3.7 million tons of smelting capacity, far more than the entire China's copper concentrate resources guarantee capacity and the international market may provide copper smelting enterprises.Copper mines in China can produce only about 40 percent of their smelting capacity."The decline in the rate of resource self-sufficiency will lead to the loss of the right to speak and control the upstream of the industrial chain of large Chinese enterprises, which will gradually become the agent processing base of international copper miners and smelters in China, endangering the sustainable development of the entire industry and adversely affecting the national strategy and economic security."Anhui tongling nonferrous metals (group) company general manager wei jianghong said.
