PROCESS FOR THE RECOVERY OF INDIUM,GERMANIUM AND/OR GALLIUM USING PHOSPHONIC GROUP-CONTAINING ION EXCHANGE PHASES

摘要

A metal chosen from the group consisting of indium, germanium and gallium is recovered from an acidic solution of these metals. The process is characterised in that it comprises the following stages: a) bringing the said solution into contact with an ion exchange phase containing at least one phosphonic group b) eluting the metals fixed on the ion exchange phase.
