ABSTRACT:
A floating method employing a cylindrical chamber having a tapered bottom to which there are secured a pipe for feeding a flotation pulp carrying mineral particles of fine fraction and a pipe for discharging gangue. Secured to the walls of the chamber is a trough for collecting froth concentrate, and a group of pulp aerators, whereas positioned axially inside the chamber is a group of tapered shells spaced equidistantly from one another with bases of larger diameter thereof facing the top part of the chamber and resting substantially at one tapered surface. Positioned over the chamber is a means for feeding mineral particles of coarse fraction in the form of a hydrocyclone, a cylindrical casing of this hydrocyclone having a pipe for evacuating the liquid phase of the floatation pulp positioned tangentially and communicating with the pipe for feeding the flotation pulp carrying mineral particles of fine fraction.
