FIELD: chemistry.
SUBSTANCE: binding composition for processing material of solid particles with formation of solid aggregated matrix is prepared including the following stages: blending of polar solvent and additional quantity of urea; addition of emulsified bitumen; addition of ureaformaldehyde precondensate; addition of other binding promotors in order to enhance bonding between the binding composition and solid particles; addition of sugar into weak organic acid; addition of weak organic acid mixed with sugar with formation of the binding composition; blending of binding composition with solid particles, which harden during over 30 minutes while mixing with above mentioned material of solid particles, besides weak organic acid is being chosen to ensure pH value of binding composition from 2.0 to 5.3.
EFFECT: binding composition was prepared for processing of materials of solid particles.
