Meeting Future Challenge in Copper Industry——Considerations on Treatment of Copper Sulfide Concentrate

Zhu Zuze

Strategic Study of CAE 2000, Volume 2, Issue 2,   Pages 87-90

Abstract:

A brief review of the advance of copper smelting technology and the price fluctuations of copper products indicate that the competition of copper market depends upon the production cost relying on metallurgy technology. In order to ensure the smooth development of the copper industry in China and win competition in the world, we must persist in domestic r & D and incorporation with foreign technology for copper smelting. This paper commentes on the deficiencies of intensified oxidizing-PS convetring-pyrorefining-electrolysis processes and analyzes the feasibility and basises of combined pyrometallurgical and hydrometallurgical method. The new combined process route will be more advantageous in future competition.
