Abstract
In a process for producing simultaneously iron or other metals and Portland cement or hydraulic lime, sufficient lime and if necessary other ingredients, such as silica or alumina, is added to the ore to give the slag the desired composition. The charge is ground to a fine powder and introduced into a rotary furnace which is heated by the combustion of pulverized fuel with the proportion of air required to obtain a carbon monoxide content of the furnace gases sufficient to prevent reoxidation of the metal and without fusion of the charge. The products leaving the furnace are cooled in a cooler, crushed and the iron &c. removed by a magnetic separator. The metal may then be melted in an electric or open hearth furnace or in a rotary furnace similar to that in which the reduction is carried out.ALSO:In a process for producing simultaneously iron or other metals and Portland cement or hydraulic lime, sufficient lime and, if necessary, other ingredients, such as silica or alumina, is added to the ore to give the slag the desired composition.
