Carbon is used in smelting systems for the two primary functions of reduction and heat generation. Depending on the nature of the smelting device, a variety of methods of introducing the carbon result. There is also a wide choice of carbon‐bearing raw materials with current emphasis on the utilization of coal. This paper analysis the underlying mechanisms for coal pyrolysis and char dissolution as they relate to the emerging in‐bath smelting systems. The influence of coal quality on process performance is discussed based on reported work in both the bench scale and pilot‐scale levels.
