Basic process of producing basic fluxed pellets for iron . A new fluxed pellet for use in iron-making is obtained by mixing and indurating about 1 to about 20 by weight of the pellet of ground melt shop slag fines with similarly ground iron ore concentrate so as to achieve particular ranges of silica content CaOSiO 2 ratio and MgO content.
The worlds resources are dominated by low-grade ore though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite.
