Optimization and Improvement of Double-Flash Copper Smelting Process in China

Based on the comparison of double-flash copper smelting process treating raw materials in foreign cases for a long time and in China case,the author is of the opinion that,under the complicated raw material conditions in copper smelters in China,the double-flash copper smelting process parameters and supporting facilities need to be optimized and improved by taking technical measures,such as changing blending mode,operating parameters and equipment structures etc.,as well as strengthening the removal of impurities inside raw materials to develop the amenability of this copper smelting process to raw materials.
