Waste Heat Recovery and Reuse of Flue Gas in Copper Pyrometallurgy

Abstract

In the paper, we take current relatively advanced, the most widely used flash smelting furnace, converter and rotary anode furnace as the examples, the waste heat resources of the process of matte smelting, the process of matte converting and the process of fire refining of blister copper in copper pyrometallurgy are analyzed respectively. Meanwhile, based on the way of using waste heat reasonably to suitable heat consumer in production process and the grade recovery principle of energy level matching, the model of waste heat recovery and reuse of flue gas in copper pyrometallurgy is constructed.
