FIELD: chemistry.
SUBSTANCE: invention relates to a method for processing nepheline raw materials and ash baked in an oven to obtain a low concentration composite flocculant coagulant. Above production process involves mixing 1–99 % of nepheline raw material and 1–99 % of ash products by weight, followed by dissolving the dry dispersion in 5–10 % sulfuric acid at a weight ratio of dry dispersion to solvent (2–5):(95–98) for 2–8 hours. Such method is environmentally safe and based on the use of secondary raw materials of mineral origin.
EFFECT: method for obtaining a low-concentration composite coagulant-flocculant based on nepheline-containing raw materials and ash is proposed.
