FIELD: chemistry.
SUBSTANCE: invention relates to the technology of production of inorganic coagulant used for wastewater treatment. Method of producing calcium aluminosilicate inorganic coagulant involves mixing the calcium-containing material with a silica-containing mineral and subsequent heat treatment. Calcium-containing material (limestone) is mixed with silica-containing mineral (kaolin) at the rate of obtaining the weight ratio CaO:SiO2 = 3.0, CaO:Al2O3 = 1.4–2.1. Mixture is fired at a temperature of from 1285 to 1300 °C for at least 10 minutes and the resulting material is ground.
EFFECT: technical result of the invention is the increase in the coagulation activity of calcium aluminosilicate inorganic coagulant and increase in the rate of sedimentation of saponite from circulating water after enrichment of diamondiferous saponite ore.
