Abstract
A process for the reduction of oxidic iron minerals in rotary tubular furnaces, with the aid of carbonaceous solid fuels and with feed of at least a part of the heat necessary for the reduction, by liquid, gaseous or pulverulent fuels, possibly with addition of lime, dolomite or the like, to fix the sulfur content of the fuel, the addition of the carbonaceous solid reductant being carried out only after the heating of the pieces of ore, preferably at a reduction temperature, characterized in that the ore is delivered to the rotary tubular furnace , without addition of the carbonaceous solid reducer, in a cut-off form with a grain size of at least 6 mm.
