The most important stage of the flowsheet is the Waelz process, which is pyrometallurgical processing in a rotary kiln at 1200–1300°C with a carbonaceous reducing agent (coke breeze). As a result, copper-containing Waelz slag is obtained with a high content of copper compared to the dust and high content of iron.
