Abstract:Continuous copper smelting technology with annual output of 300 kt is a major technological innovation. Process, equipment, technical characteristics and production operation of hot state continuous copper smelting furnace were introduced. In the past year, system operation rate was more than 97.5%, grade of matte was 73%—76%, slag Fe/SiO2=2, sulfur content of crude copper was less than 0.03%, and copper content of anode copper is more than 99.3%. Production practice has proved that this technology has the characteristics of strong adaptability of raw materials, big capacity, low production cost, good working environment, high degree of automation and low investment.
