Reagents used in processing should be sourced closer to the smelter. Furthermore, clustering synergistic industries, where one plant uses the products of another, would be ideal, e.g. integrating a FeMn smelter with a steel plant (Kitamura, 1983; Yamamoto et al., 1986). It was proposed that fines/slimes be transported pneumatically.
