METHOD OF SCHUNGITE TREATMENT Russian patent published in 2012 - IPC C01B31/00 C09C1/44 

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.
