FIELD: water and air purification technology.
SUBSTANCE: group of inventions relates to a method of treating waste water, use of an additive for flocculating solid particles, use of a sulphonated dispersant and an additive for flocculating solid particles for treating waste water. Method of treatment of waste water containing fresh tails, small tails, stale small tails (SST) or stale small tails (SST), containing clay in amount of 5 to 70 wt %, and containing solid particles includes addition of at least one sulphonated dispersion additive to effluents; then adding at least one additive for flocculation of solid particles.
EFFECT: technical result consists in accelerated treatment of mine wastes by increasing their deposition rate for efficient water recycling and volume reduction of wastes.
