Abstract

The present invention discloses a system and a process for dry dressing of iron-oxide-ore fines and superfines present in dump barrages and low-content ore dump, which comprises a hot-air injection dryer (9) with mechanical stirring means and shafts provided with blades (9.2) for disaggregating and moving the material in the horizontal and vertical directions; a set of air classifiers operatively connected to the outlet of the dryer, which carry out the classification of the fine and superfine iron ores into pre-determined granulometry ranges; and magnetic separators (13, 16, 19) with magnetic rollers (32, 42, 47) arranged in cascade, formed by rare-earth magnets of low and/or high magnetic intensity, the magnetic rollers being arranged at a determined inclination angle.
