Pyrometallurgical Process an overview | ScienceDirect Topics

Roasting, smelting, and converting are pyrometallurgical process steps that are based on the relative affinities of metals for sulfur and oxygen. A typical process flowsheet is shown in Fig. 1.Iron sulfide is primarily converted to oxide in roasting. When only about half the iron is oxidized during roasting, less nickel and copper sulfides are oxidized.
