- Abstract
We describe the use of sulfiding agents to achieve a significant increase in the level of metal recovery during the smelting of copper concentrates and matte conversion. In the conversion process for copper and polymetallic mattes, the addition of sulfides produces (1) a remarkably low level of nonferrous metals remaining in converter slag; (2) a high level of copper extraction to matte; (3) high levels of arsenic and antimony extraction to dust; and (4) a decrease in the magnetite content of the converter slags. Based on laboratory, pilot, and industrial scale data, the advantages of the addition of sulfiding agents to the converter for the treatment of copper and polymetallic materials are demonstrated.
