COMPOSITIONS COMPRISING PROTEINS AND METHODS OF USE THEREOF FOR RARE EARTH ELEMENT SEPARATION
Document Type and Number:
WIPO Patent Application WO/2022/266120
Kind Code:
A3
Abstract:
Methods and materials are provided for the preferential separation of rare earth elements (REEs) from non-REEs in REE-containing materials and separation of certain REEs from other REEs, both individually and in groups. Such methods include steps of (a) providing a protein that can selectively bind one or more REEs; (b) contacting the protein with the REE-containing material, wherein the protein binds at least a portion of the one or more REEs to form one or more protein-REE complexes and an REE-depleted material; (c) separating the one or more protein-REE complexes from at least a portion of the REE-depleted material; and (d) separating the one or more REEs from the protein to produce a purified fraction of the one or more REEs and a regenerated protein.
