Description

This invention relates to the beneficiation of minerals.

The purpose of the invention is to increase the separation efficiency in the separation of gas-hydrated mixtures by increasing the time of exposure of the traveling magnetic field to conductive particles.

The drawing shows the separator section.

The separator includes a housing 1 made of a non-magnetic material in the form of a pipe, one (lower) end of which is connected to the receiver 2 of an electrically conductive fraction, to the opposite side through a pipe 3 to a receiver (not shown) of the non-conductive fraction (enrichment tails). The receiver 2 is made, for example, in the form of a lock feeder capable of continuously collecting the electrically conductive fraction from the separator. Outside the housing 1, an inductor 4 is disposed, consisting of individual coils connected to a power source (not shown) for creating a traveling magnetic field in the direction coinciding with the direction of feed of the source material to the inductor and opposite to the flow leaving it.

The coils of the inductor 4 are connected by an external magnetic conductor 5. Inside the housing 1 there is installed an annular gap 6 to it a branch pipe 6, through which the raw material is presented, presented as a stream of hydro (gas) mixture of conductive and non-conductive fractions

with liquid or gas. In this case, solid electrically conductive particles are suspended in the flow of liquid (gas). The nozzle 6 is made of non-magnetic material. Inside the pipe 6 is fixed magnetic core 7 on the brackets 8 with an annular gap to the surface of the pipe. The magnetic core 7 is made of laminated electrical steel sheet.

The separator body is under pressure during operation at the hydro (gas 6) mixture. The inductor axis can be located at any angle to the horizon. The optimal position of the inductor is vertical. The arrows in the drawing show the direction of movement of the magnetic field.

The separator works as follows. ;.

The source material in the form of a stream of hydro-. The ro (gas) mixture enters the nozzle 6, the zone of action of the traveling magnetic field created by the inductor 4. When moving in the nozzle 6, the electrode particles receive accelerated translation relative to the non-electrode fraction of the source material under the influence of the running magnetic pops, the receiver is trapped them and removed. ,

In this way, rebating is carried out already in the nozzle. Further, the flow of the source material turns from the receiver in the opposite direction — into the annular cavity between the housing and the nozzle.

At the same time, a certain amount of electrically conductive particles, not deposited in the receiver, is entrained by the flow of liquid (gas) and is again subjected to the action of a traveling magnetic field. Since the movement of the magnetic field now acts in the opposite direction to the flow, the electrically conducting particles are decelerated by the traveling magnetic field, lagging behind the flow velocity, stop and precipitate into the receiver 2.
