METHOD OF DEPOSITION OF SAPONITE PULP WITH THE USE OF CALCIUM ALUMINUM SILICATE REAGENT Russian patent published in 2018 - IPC C02F1/52 B01D21/01 C02F101/10 C02F103/10 

FIELD: mining industry.

SUBSTANCE: invention can be used in the field of the mining industry in the enrichment of diamondiferous kimberlite rocks. Method includes removing saponite-containing substances from the circulating water by the method of sedimentation. Pulp with a particle size of 71 mcm and a suspended matter content of 90 g/l is diluted with water in a ratio of 1:5, intensively mixed for 5–7 minutes. Resultant mixture is precipitated for 120 minutes due to the introduction of calcium aluminosilicate reagent composition, wt. %: CaO - 63–66; SiO₂ - 21–24; Al₂O₃ - 4–8 % and Fe₂O₃ - 2–4 % in an amount of from 2 to 5 g per 400–500 ml of diluted pulp.

EFFECT: method provides an increase in the rate of thickening of the pulp during settling, reducing the consumption of fresh water and eliminating the discharge of industrial waste.
