Anode copper is the final product from pyrometallurgical process and the feed for electrorefining process. In conventional process there are four oxidation steps and one reduction step to produce anode copper from the concentrate in three furnaces. Three types of slags are produced from the process that required further treatment to recover copper. Following the successful installation of the first bottom blown copper smelting furnace in 2008, Dongying Fangyuan Nonferrous Metals recently developed a simplified process to make anode copper. In the new process, only two custom-designed furnaces are used to replace conventional smelting, converting and refining furnaces. First furnace continuously produces high grade matte (> 75 wt% Cu) which contains little iron (< 2 wt% Fe). The liquid matte continuously feds into the second furnace to produce anode copper. The new process significantly reduces the costs of capital and operation, and also increases the productivity and environmental sustainability.
