FIELD: process engineering.
SUBSTANCE: invention relates to processing of carbon-containing rock, i.e. schungite. Proposed method comprises crushing and sizing schungite to 0.1-10 mcm-particles and dispersing in water using 1-3 mm-grinding bodies with the ratio of grinding body weight, schungite weight and water weight making 3.0-7.0:0.5-1.5:5.0-8.0 for 1-2 hours. Then, obtained mass is filtered and dried in natural conditions.
EFFECT: multifunctional product consisting of filler and pigment with particle size of 0,01-1 mcm, specific surface of 100-130 m2/g and catalytic activity in ozone decomposition reactions of 2*1018-5*1018 molecule/g*s.
