Flotation machine

A flotation machine comprises a cylindrical chamber (1) having a tapered bottom (2), a pipe (7) for feeding a flotation pulp containing fine mineral particles and a pipe (6) for discharging gangue. At the upper zone of the chamber (1) is a trough (8) for collecting froth concentrate; also provided i...

Zusammenfassung:	A flotation machine comprises a cylindrical chamber (1) having a tapered bottom (2), a pipe (7) for feeding a flotation pulp containing fine mineral particles and a pipe (6) for discharging gangue. At the upper zone of the chamber (1) is a trough (8) for collecting froth concentrate; also provided is a group of pulp aerators (17) and, arranged axially inside the chamber (1), a group of tapered shells (10) spaced equidistantly axially of the chamber (1), bases of larger diameter of these shells (10) facing the top part of the chamber and defining a tapered surface (M1), and one more group of tapered shells (11) arranged at the top part of the chamber (1) outside the shells (10) of the first group, bases of smaller diameter of the shells (11) facing the bottom (2) and defining another tapered surface (P). Overlying the chamber (1) is a means (34) for feeding mineral particles of coarse fraction.
