China ENFI Engineering Corporation and Yantai Guorun Copper Co., Ltd. have jointly developed the copper smelting technology by three continuous furnaces in thermal operation which means oxygen-enriched side-blowing smelting furnace—multi-lance top-blowing continuous converting furnace—pyrometallurgical anode refining furnace. After more than three years of stable production and continuous optimization, this technology is recognized by the industry as having reached the international advanced standard. This paper reviews the development background, performance history, and innovation and optimization in the industrial application of this technology, introduces its characteristics, and prospects the development direction of this technology.
