Review and thermodynamic analysis of As (arsenic) in copper …

Increasing content of As (arsenic) in Cu concentrates remains problematic for the pyrometallurgy of copper. Many approaches are used to eliminate it from the process streams: partial roasting of concentrates before smelting; eliminating to the gas phase during the smelting followed by the processing of dust; chemical fixation of arsenic in the …

Thermal Processing: Pyrometallurgy—Non-ferrous

Abstract. Metals and metallurgy have played a pivotal role in the development of human civilization. The major periods in history are marked by such names as the Bronze Age and the Iron Age to reflect the importance of metals. The history of pyrometallurgy can be traced back at least 6000 years to the simple copper smelters of present-day Israel.
