Title:
ALKALI METAL AND/OR ALKALI EARTH METAL EXTRACTION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/007331
Kind Code:
A1
Abstract:
This alkali metal and/or alkali earth metal extraction method is superior in terms of cost and allows repeated use of the aqueous solution that extracts alkali metal and/or alkali earth metal from a solid. This method is for extracting alkali metal and/or alkali earth metal from a solid containing an alkali metal and/or alkali earth metal, and involves an elution step in which the solid is added to an amino acid-containing aqueous solution, and the alkali metal and/or alkali earth metal is eluted into the amino acid-containing aqueous solution.
