FIELD: metallurgy.
SUBSTANCE: invention relates to a method of treating an impurity-containing carbonaceous bulk material. A method of treating an impurity-containing carbonaceous bulk material comprising at least one material from a group consisting of broken cathodes of equipment for producing aluminium from a melt, broken anodes, broken carbon linings of steel furnaces, cupola furnaces or melting furnaces for other metals, glass furnaces, furnaces for melting ceramics and other carbonaceous bricks to be treated, wherein to obtain purified carbonaceous bulk material, an impurity-containing carbonaceous bulk material is directly inductively heated in a reactor, wherein to carry out continuous treatment, bulk material used contains up to 50 wt.% of grains with a size of more than 30 mm, inductive heating is performed with frequencies between 1 kHz and 50 kHz and maximum reactor temperature is set to 2,500 °C.
EFFECT: technical result is high efficiency of treating carbonaceous material.
