摘要

The invention relates to the hydrometallurgy of rare-earth metals and can be used for the preparation of germanium concentrates from the industrial solutions. A method for germanium extraction from the ammonia-tar liquor of by-product-coking industry provide for ion-exchange treatment of the last with anionite. A highly basic spatial cross-linked polymer of macroporous structure containing quaternary nitrogen atom is used as an anionite. The use of the method provides effective germanium extraction.
