METHOD OF PROCESSING POTASSIUM-CONTAINING WASTE OF MAGNESIUM PRODUCTION FOR FERTILIZER Russian patent published in 1995 - IPC

Abstract RU 2049764 C1

FIELD: technology of complex fertilizer production. SUBSTANCE: spent electrolyte of magnesium electrolyzers is mixed with pulp containing aqueous chloride solutions. Neutralized potassium-containing sewers (up to pH 8-9) formed after aqueous-soda scrubbing at carnallite dehydration were used as pulp. Preliminary sewers were mixed with lignosulfate at the mass ratio 1: (2.5-3.5), and spent electrolyte is preliminary mixed with carnallite dust formed after dry scrubbing at carnallite dehydration at the mass ratio (8-9): 1. Dynamic strength of granules is 87-95% Fertilizer is effective on sandy loam soils with relation to food cultures. EFFECT: improved method of processing. 2 tbl
