Abstract
This disclosure relates to a water-less extraction process to collect clay, silica and iron ore from tailings taken from tailings dams and deposits by drying, dry sifting, density separation, mechanical friction separation, air classification separation, milling and magnetic separation. This is achieved by using pieces of equipment arranged in sequential order, as follows: a horizontal rotary sieve (4) with a classifier equipped with up to five outlets for the discharge of particles of several different sizes; a horizontal concentrator (5) equipped with blades (5.3) and fins (5.2) for the removal of clay, that is connected to an exhaust system (3); a vertical air concentrator (5) for dry separation of clay by centrifugal force, linked to a second exhaust system (7) in addition to a magnetic separator (8) that improves the performance when extracting materials.
