FIELD: mining and processing industry.
SUBSTANCE: invention relates to primary processing of ore by dry dressing. Device comprises inclined housing from non-magnetic material with inner channel. Housing is equipped with a loading branch pipe for supply of ore particles, a medium input device, an ionizer. Cold plasma generator is used as the medium input device. In the channel of the housing there is a flow divider and in series, on the outer side of the housing, an ionizer is installed. Electric inductor is located behind the ionizer outside the housing, coaxially with the housing. Valve regulating the area of the outlet section of the internal channel is installed at the outlet of the housing. Housing is installed at an angle to horizontal line exceeding angle of natural slope of processed ore by 3–5°.
EFFECT: higher degree of charge of ore particles.
