铜冶炼工艺技术的进展与我国铜冶炼厂的技术升级

Advances in Copper Smelting and Converting Process and Technical Upgrading in Chinese Smelters

20世纪70年代以来世界铜冶炼工艺技术发展很快,出现了很多新工艺并应用于工业生产;20世纪90年代开始我国老的铜冶炼厂均先后进行了技术升级改造,进入21世纪后又建设了很多新的铜冶炼厂,均采用先进冶炼工艺;2008年以后国内自主开发的铜冶炼新工艺得到迅速推广应用。综述了世界铜精矿熔炼和铜锍吹炼的技术进展,回顾了我国铜冶炼厂技术升级的历程,总结了我国铜冶炼厂冶炼工艺选择的经验,对我国铜冶炼项目的冶炼工艺选择提出了建议。

Copper pyrometallurgical technology in the world enjoys a rapid development since 1970’s with many new processes emerging and being commercialized.Since 1990’s,all the existing copper smelters in China had completed their technical modernization.Entering 21 century,many new copper smelters has been constructed and commissioned in China with state-of-the-art processes employed.The domestically-developed new smelting and converting processes have been widely applied in China since 2008.Technical advances in copper concentrate smelting and matte converting in the world are summarized.The course is reviewed in terms of technical modernization of Chinese copper smelters.Experience in smelting and converting process selection for technical upgrading project of Chinese copper smelters is summarized.Some proposals are put forward in process selection for new smelter projects.
