PROCESSING METHOD OF DISPERSE MINERAL RAW MATERIAL Russian patent published in 2019 - IPC H05B7/20 H05H1/42 C22B9/22 

FIELD: metallurgy.

SUBSTANCE: invention relates to plasma technology in metallurgical production, namely, to methods and devices for processing disperse materials, and can be used to produce pure elements. Method of plasma processing of dispersed mineral raw material includes introduction of powdered material into plasma jet with reducing gas with subsequent evaporation and condensation of material, for which a plasma reactor is used, which contains a raw material bin with a safety valve, connected through gas-vent channels and channels for supply of raw material with a reducing chamber, made in the form of a closed toroidal channel, along the bottom of which there is a slot for exit and collection of the end product in the crucible, at that, in the chamber there are at least two plasmatrons for tangential blowing of the plasma flow, and channels for supply of raw material are made perpendicular to direction of plasma flow, for this purpose, raw material is continuously supplied under plasma jet in closed circulation channel of chamber until final reduction and condensation of metal.

EFFECT: disclosed is method of processing disperse mineral raw material.
