Definitions

  • the present invention relates to the field of processing non-ferrous metal ores, in particular to a flotation machine for processing non-ferrous metal ores using the flotation process.
  • the invention is to be used in the processing of ores in which the material to be processed is contained in finely comminuted form and in which the mineral particles are not completely separated from the bedrock.
  • this invention can be effectively used in the flotation of coal, mining chemical raw material and water purification.
  • the industrial operation of modern constructions of flotation shows that in the processing of the identical raw material, the specific power of the Flot a - tionsmasohinen having different types are no significant differences.
  • the flotation time is essentially determined by the type of material to be floated and not by the type of flotation machine used.
  • the flotation machines with a high individual output the introduction of which is currently solving the task of increasing the capacity of the floor chambers of processing plants, have a specific performance that corresponds to the flotation machines of low volume. In this way, the inclusion of difficult-to-float, muddy oxidic ores in the areas of industrial production and the expansion of the scope of the raw material to be processed requires a considerable increase in the effective space of the chambers of the flotation machines.
  • a flotation machine is known (US, A, 3446353), in which a nozzle, a bath and an outlet line The main components are.
  • the nozzle is constructed in such a way that an air jet is fed to the center of the jet, while the slurry moves through guides which give it a rotary movement in the form of a ring.
  • the nozzle directs the swirled concentric jet of the mixture of turbid and compressed air into a chamber.
  • the central air jet is rotated together with the surrounding turbidity. It is precisely this interaction of turbidity and air within the nozzle that causes the bubbles to detach from the "air core" and ensures good mixing and contact between air bubbles and mineral particles.
  • the jet consisting of the mixture of water and air, which has traveled a distance sufficient to completely disperse the air (the speed of the jet decreases several times), flows around a partition.
  • This partition absorbs the jet energy and ensures the creation of secondary flows around the primary mixing zone in the opposite direction, i.e. towards the opening of the nozzle.
  • the turbidity first rises, then moves in the horizontal direction and then finally descends down into the ventilation zone, where the "bubble - particle" aggregates separate from the turbidity flow.
  • the vent zone is four to six times larger than the primary.
  • a flotation apparatus is also known (DE, A, 1067743), which has a cylindrical agitator chamber in which the height of the slurry column is 1.5 to 3.5 of the chamber width, and a pump by means of which the slurry to be floated together with the Air is conveyed into the agitator chamber.
  • An additional cone is mounted above the agitator chamber, which has an overflow for the partial discharge of the sludge flowing in from the agitator chamber.
  • a major disadvantage of this flotation machine is an uneven filling of the cross section of the jet moving in the agitator chamber with air bubbles.
  • a flotation machine No. (US, A, 4490248) is known, which comprises the following main components: a mixing chamber which represents two truncated pyramids which face each other with the larger base areas and are arranged one above the other, a nozzle mounted in the mixing chamber, an impact wall, which is located in the mixing chamber in the immediate vicinity of the outlet opening of the nozzle and is normal to the axis of the latter, a riser chamber which is in the form of a truncated pyramid or a truncated cone which, with its smaller base, faces the mixing chamber, is formed and communicates with the latter, but has in its upper part with a vent chamber, a vent chamber, which is arranged adjacent to the riser for lifting the slurry and means for removing the contains in the vent chamber forming means, means for discharging the residual product.
  • the slurry is premixed with the air to form a slurry-air mixture, which is then fed through the nozzle into the lower part of the mixing chamber under pressure, the slurry-air mixture being directed at right angles to the baffle that is in the mixing chamber in the immediate vicinity of the nozzle mentioned.
  • the currents in the upper part of the mixing chamber meet at an angle of 40 to 75 ° to the vertical axis of the mixing chamber, while the speed when the currents meet is 90 to 100 cm / s. Furthermore, the cloudy-air mixture rises in the riser chamber and flows out into the ventilation chamber directly under the foam layer.
  • a disadvantage of the flotation machine in question is that when the cloudy-air mixture impacts the impact wall, the impact energy of the jet is often not sufficient to produce bubbles, the size of which satisfies the requirements of rapid flotation. At the same time, the baffle wall is subjected to rather rapid hydroabrasive wear.
