迎接铜工业挑战——低成本处理硫化铜精矿途径的思考

Meeting Future Challenge in Copper Industry——Considerations on Treatment of CopperSulfide Concentrate at Low Cost

对过去10年来铜冶炼的技术进步和铜价格的变化作出的简要回顾指出,未来铜市场的竞争是取决于冶炼技术的生产成本的竞争。坚持自我研究开发和引进相结合才能保证我国铜工业健康稳定发展,并能应付国际竞争。评述了现在强氧化—PS转炉吹炼—火法精炼—电解流程的不足;分析了火湿法联合流程的可能性及依据;新的火湿法联合流程将有更强的竞争优势。

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. [
