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, CaO/SiO 2 ratio, and MgO content. The melt shop slag fines have been considered a waste material, but contain significant slag and metal values.
