Abstract

The present invention relates to a hydrometallurgical process for isolating tantalum and niobium from raw materials containing tantalum and niobium by treatment with pure hydrofluoric acid or a mixture of hydrofluoric acid and sulphuric acid, followed by solvent extraction of the tantalum and niobium fluoro-complexes from the treatment solution using methylisobutyl ketone (MIBK) and steam distillation of the organic ketone phase containing tantalum and niobium, to produce a new aqueous which is contactable by fresh MIBK to selectively extract tantalum.
