Title:
METHOD FOR EXTRACTING AND SEPARATING RARE METAL IN VARIOUS ACID SOLUTION USING SULFUR-BASED EXTRACTANT
Document Type and Number:
Japanese Patent JP2016191136
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for simply separating rare metal by solvent extraction using a specific extractant containing a sulfur atom.SOLUTION: Rare metal is extracted and separated by a method (liquid separation) for extracting and separating rare metal contained in various acid solutions using N,N,N',N'-tetraalkyl thiodiglycol amide (S-DGA) represented by S(CHCON(R))(R is alkyl group having 1 to 12 carbon atoms) as an extractant, or a method (solid liquid separation) for extracting and separating rare metal by passing various acid solutions containing rare metal through a solid adsorbent formed by impregnating N,N,N',N'-tetraalkyl thiodiglycol amide (S-DGA) represented by S(CHCON(R))(R is alkyl group having 1 to 12 carbon atoms) with a resin.SELECTED DRAWING: Figure 1
