The dry mixture that results from the blending of iron-rich oxide dust and other such wastes carbonaceous material is heated to release the volatiles with agglomeration. It is subsequently loaded into a preheated furnace with rotary hearth and heated for 5-12 min at 2150-2350ยฐF for smelting and discharging the metalized product suitable for recycling. The dry mixture is briquetted at >lO,OOO psi, and the briquettes are smelted at the nominal CO/CO: ratio of 2-5 for the reduction of metal oxides. The metalized Ferich briquettes are suitable for recycling to the steelmaking plant.
