HIsmelt is a direct smelting process based on coal-derived syngas. In this process, iron ore particles are preheated and pre-reduced in circulating fluidised bed reactors integrated with two-stage cyclones, as shown in Fig. 3 a (Orth et al., 2007). After that, the hot ore is transferred to a smelter to produce liquid iron.Web
