PROCEDURE FOR THE RECOVERY OF GERMANIUM IN DISSOLUTION BY COMPLEXING AND USING ION EXCHANGE RESINS.

摘要

The invention relates to a method for the recovery of germanium present in aqueous solutions, which is separated form other materials also present in said solutions through the use of ion-exchange resins. The selective extraction is performed by forming an organic germanium complex which is absorbed in a conventional anionic resin. Finally, the germanium is desorbed from the resin when the resin is brought into contact with an aqueous solution which can be an acid, base or neutral solution. The possibility of selecting a desorption solution facilitates the possible subsequent operations for obtaining germanium of higher purity. Following desorption, the resin can be regenerated for a new use.
