The invention relates to the enrichment of minerals, namely, to designs of pneumatic column flotation machines and can be used in flotation processing plants.

The purpose of the invention is to increase the extraction of the useful component in the concentrate due to the selective flotation of mineral particles with different degree of floatability.

The drawing shows the proposed device.

The device comprises a chamber 1 of a column machine installed at an angle of 25-70 to the horizontal plane, a loading device 5 of the device 2 located in the upper part of the chamber 1 of the machine under the device 3 for unloading the foam product, aerators 4 made in the lower part of the chamber 1 of the machine chamber product, fixed under the aerators 4, foam receivers 6-8 for fractional unloading concentrate flotation vertically mounted on the height of the camera 1 of the machine perpendicular to the horizontal plane measuring The installation of them and articulated elastic cuffs 9 with the camera body 1 of the machine. This joint provides the ability to change the angle of installation of foam receivers 6–8 for fractional unloading-floated particles on air bubbles rising from А 4, are unloaded through fixture 3. Hard-floated particles are fixed on air bubbles supplied from А 4 and 10, and depending on The degrees of flotation are selectively unloaded through one of the P 6 - 8. If necessary, change the azrohydrodynamic x-k process with the help of the tool 14. Change the angle of inclination K 1. At the same time, the system of blocks 13 installs П 6 - 8 perpendicular to the horizontal plane. 3 hp f-ly, I ill.

concentrate on floatability relative to the horizontal plane. The pneumatic column of the flotation machine contains a partitioned aerator 10, located at the height of the chamber 1 of the machine, each of the sections of which is equipped with a nozzle 11 for supplying air with a valve 12. The chamber body of the machine 1 and foam receivers 6-8

 The bottom fractional discharge of the concentrate by floatability is kinematically connected through a system of blocks 13 to a device 14 for changing their angle of inclination.

The device works in the following 1M way.

The original slurry, pre-treated with reagents, enters the machine chamber 1 through the loading device 2. The lightly floated particles on the air bubbles rising from the aerators 4 are unloaded through the device 3 to unload the frothy product. The hard-to-floatable particles move — along the chamber 1 of the machine and, as they move, they are fixed on the air bubbles supplied from the aerators 4–10. At the same time, depending on the degree of floatability of the particles, their selective unloading is performed through one of the 6.7 or 8 foam receivers for fractional discharge of the concentrate along

fit The waste rock is removed from the chamber 1 of the machine through the discharge device 5 of the chamber product 5. The flow rate of air supplied to each section of the aerator 10, located along the height of the chamber 1 of the machine, is controlled by means of valves 12.

When changing the type of enriched material (mining and chemical raw materials, polymetallic ores, etc.) and the conditions of conducting the flotation process, the need arises to change the aero-hydrodynamic characteristics of the process in the chamber 1 of the machine. To do this, using a tool 14 dp for changing the angle of inclination of the camera I of the machine, adjust the angle of inclination of it. At the same time, the system of blocks 13 provides for installation of foam receivers 6–8 for fractional unloading of concentrate along floatability perpendicular to the horizontal plane. In this case, a winch is used as a device 14 dp for changing the angle of inclination of the chamber 1 of the machine.
