<p>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/Si02 ratio, and MgO content. The melt shop slag fines have been considered a waste material, but contain significant slag and metal values. The slag is already in calcined form for an energy saving as compared to the use of limestone and dolomite, and is already somewhat divided for a saving in grinding energy. The resultant basic pellets have better furnace properties than the acid pellet produced without slag addition.</p> |
