What factors affect the price of copper?

Copper moves around the world in a variety of forms such as copper ore, copper, refined copper and copper wire. Chile and Peru are the largest exporters of copper ore, while China and Japan

COPPER Copper production - Repository

ores are processed directly to impure black copper 95 wt % Cu and to a copper-rich slag. The two ore types can be smelted together to produce matte and a slag with low copper content. Another product is top gas, which contains flue dust. Ores that contain high concentrations of arsenic and antimony also form speiss, which is difficult to

The Importance of Copper In China’s Economy Institutional

Currently, China is the world’s biggest importer of copper by some margin, accounting for 43% of global copper ore imports – more than three times the level of Japan in second place.

Assessing the environmental impact of metal production

While the average grade of copper and nickel ores in Australia currently is relatively high up to 3% and 2.3%, respectively – see Table 1 , the potential effect of depleting ore grade is illustrated in Fig. 11 for copper production by the smelting and electro-refining route and nickel production by the smelting and Sherritt-Gordon refining
