Hydrometallurgical Production of Niobium and Tantalum Oxide

A hydrometallurgical process for the production of niobium and tantalum oxide from a primary mineral resource and by product of a tin smelting slag is proposed. This process comprises dissolution of the concentrate and slag with the mixture of acids, following by purification and precipitation process. XPS do not have any background in hydrometallurgical recovery of niobium and tantalum and therefore this will provide an important foundation for future work by XPS in this field.
