Abstract

A flotation machine for recovering valuables or concentrates from a raw material, which comprises: a flotation cell having at least one froth-discharging opening located at the lower part of a side wall of said cell; an agitating means fitted within the central part of said cell; and at least one froth-discharging pipe fixed within said cell, the one end opening of said pipe being connected with said froth-discharging opening of said cell and the other end opening of said pipe being held at a level lower than the upper end of said side wall but higher than the surface level of the pulp or liquid charged to be subjected to flotation, thereby forming at least one froth-discharging passage within said cell.
