METHOD OF OBTAINING ALUMOSILICON FLOCCULANT-COAGULANT Russian patent published in 2016 - IPC C01F7/74 C01B33/26 C02F1/52

Abstract RU 2588535 C1

FIELD: chemistry.

SUBSTANCE: invention relates to video processing alumosilicic material to produce alumosilicic flocculant-coagulant to obtain dry product. Processing of nepheline concentrate ((Na,K)₂O·Al₂O₃·2SiO₂) with aqueous solution of sulphuric acid, wherein 7-11 % sulphuric acid is taken and mixing for 30-40 minutes. That is followed by dehydration in screw reactor when introduced into prepared solution of aluminium hydroxide with simultaneous mixing and then final strengthening of suspension with concentrated sulphuric acid to achieve density suspension of 1.3-1.4 g/cm³ and spontaneous crystallisation of product.

EFFECT: invention enables to obtain solid alumosilicic flocculant-coagulant with high content of active component of up to 16 % by Al₂O₃.
