Title:
METHOD FOR RECOVERING MAGNESIUM BY USING SEDIMENT AND SULFURIC ACID GENERATED IN ELECTROLYTIC CHLORINE GENERATION SYSTEM USING SEAWATER AND BRACKISH WATER
Document Type and Number:
WIPO Patent Application WO/2023/136569
Kind Code:
A1
Abstract:
The present invention relates to a method for recovering magnesium from sediment generated in an electrolytic chlorine generation system using seawater or brackish water, the method comprising the steps of: eluting magnesium by using sulfuric acid in magnesium hydroxide, which is sediment generated in an electrolytic chlorine generation system using seawater and brackish water; precipitating magnesium sulfate by adding an organic solvent to a magnesium-eluted solution; and after the precipitation of the magnesium sulfate, separating the organic solvent and sulfuric acid by using a vacuum evaporation method, and reusing the organic solvent.
