Add to ORKGReport discussing methods for the "separation of tantalum and tuballoy from used tantalum K's. These methods are: hydrofluorination, fluorination, hydrochlorination and dissolution in hydrofluoric acid -- nitric acid, hydrofluoric acid -- hydrochloric acid mixture, and hydrofluoric acid alone.
