PROCEDIMIENTO DE CONTACTO FLUIDIZADO, CON PARTICULAR APLICACIËN AL BENEFICIO DE LOS MINERALES SULFURADOS

摘要

Apparatus for interacting particulate material with gas in which particulate material is fed into one end of an elongated chamber and discharged from the opposite end thereof, while gas under pressure is fed through the perforated bottom wall of the chamber so that the particulate material fed into the chamber will form a fluidized bed of such material therein which flows from the one to the opposite end of the chamber. The space in the chamber immediately above the bed is divided by a plurality of transverse partition in successive zones preventing particulate material which is carried by the gas upwardly out of the fluidized bed to pass from one to another zone while permitting unobstructed flow of the material in the fluidized bed from one to the opposite end of the elongated chamber to assure thereby uniform treatment of the particulate material during its pasage through the chamber.
