ABSTRACT:
Method of and apparatus for the flotation processing of minerals. The starting material is pretreated by means of flotation agents and is then spread in the form of a controllable thin film over a fixed perforated controllable-surface drum, the so-obtained suspension-film is blown through by an airstream from the inner to the outer side of said drum, and the stability or the composition of the frothed layer or of the unfrothed layer over the surface of the suspension is controlled.
