FIELD: chemistry.
SUBSTANCE: invention can be used in processing of paper or plastics, concrete, in production of paints or in agriculture. Method of obtaining self-binding pigment particles includes supply of water suspension of mineral pigment material and at least one polymer binding agent. Said binding agent contains at least one modified polysaccharide, representing carboxymethylcellulose, and has carboxylation degree 0.4-2.0 and intrinsic viscosity from >300 to 500 ml/g. Binding agent is added to water suspension of mineral pigment in amount 0.1-10 wt %, counted per the total suspension weight, and mixed. Content of solid substances in obtained suspension constitutes from ≥45 to 95 wt %. Obtained suspension of mineral material is grilled.
EFFECT: invention makes it possible to obtain pigment suspensions with high content of solid substances with reduction of quantity of applied combustible binders and elimination of concentration stage.
