1. A method for pneumogravitational separation of valuable mineral substances from loose material, characterized in that the loose material is delivered to the flotation chamber of the separating device, whereas that device has one at least inlet and numerous outlets, and the flotation stream can flow from one at least inlet to one at least outlet, and in that chamber, the raw material is floated by contacting the flotation stream featuring a determined air flow speed being sufficient to divide the raw material in one at least valuable mineral fraction, whereas that mineral fraction is separated from the flotation stream by the weight of the valuable mineral content, and the waste fraction remains in the flotation stream, and then, this one at least separated valuable mineral fraction gathers at one outlet of the flotation chamber, and the waste fraction gathers at another outlet of the flotation chamber.18. A device for the pneumogravitationally separating valuable mineral substances from loose material, characterized in that includes a flotation chamber (54) of an oblong shape, and in the casing (52), it has the first inlet (60) and the first outlet (70),...<IMAGE>
