of reduction of raw ilmenite is lower than the pre-oxidized ilmenite pellets. It is well-known that the reduction in pellets with any carbonaceous material inside it follows topo-chemical reactions.... Some researchers have also suggested that the topo-chemical reactions start in parallel at several locations within the composite pellet [20, 40]. Besides, many researchers have worked on the reduction......
