ABSTRACT:
Apparatus for treating iron ore, comprising an elongate and generally cylindrical inclined kiln mounted for rotation about its longitudinal axis. A drive motor is coupled to the kiln to rotate the latter about that axis. A moving grate is positioned at the upper end of the kiln to feed iron ore pellets into the kiln while the latter is rotating. Port-defining means are provided in the generally cylindrical wall of the kiln to enable gaseous material to be fed into the interior of the kiln at at least one position between the ends thereof. The port-defining means are of such a construction that they are open when they are underneath the iron ore in the kiln. Gaseous oxidizing material feed means are connected to the port-defining means to feed such oxidizing material thereto, whereby oxidizing gaseous material is passed through the iron ore in the kiln when the apparatus is in use so as to raise the temperature of the iron ore, by oxidation thereof, and cause the latter to be indurated. The rate at which gaseous oxidizing material is fed to the port-defining means is dependent upon the interior temperature of the kiln.
