ABSTRACT:
A process of selectively separating a target metal contained in a solid matrix from the solid matrix by contacting a solid matrix containing a target metal with an aqueous solution including a water-soluble polymer adapted for complexation with the target metal for sufficient time whereby a water-soluble polymer-target metal complex is formed, and, separating the solution including the water-soluble polymer-target metal complex from the solid matrix is disclosed.
