Abstract
An agitation flotation cell for the preparation of minerals and coals having a vertical rotatable shaft surrounded by an air intake pipe with upper and lower annular plates coaxial with the shaft each having central agitation intake openings and an agitator carried on the shaft between the plates including a plurality of outwardly extending agitator paddles having axially facing surfaces with the paddle surfaces positioned at different oppositely disposed angles relative to an orbit plane at right angles to the axis of the shaft producing opposed axial thrust forces on the material agitated in the shaft with radially extending vanes between the paddles with the vanes being substantially parallel to the shaft.
