FIELD: construction.
SUBSTANCE: method of processing of "dust" of dump steel-smelting slag comprising separation of magnetic substance from non-magnetic slag "dust" is crushed down to the specific surface 400-450 sq.m/kg, then by a constant magnetic field with the intensity 850-1000 kA/m the magnetic substance is separated from non-magnetic substance, the non-magnetic substance is wetted with water amounting 3.0-4.0 by weight % of the weight of non-magnetic substance containing H2CO3 carbonic acid 0.0033-0.0065 by weight % of the weight of non-magnetic substance then it is mixed with liquid glass 5.0-20.0 by weight % of the weight of non-magnetic substance with obtaining of granules and then it is subjected to compression with a pressure from 100 MPa up to 250 MPa in a stamp.
EFFECT: acceleration of strength accumulation.
