Based on these results and the work of other authors, we deduced that clean-up operations might be adequate for Ta extraction from most of the tantalite deposits in Nigeria. The consideration of simplicity and cost of process favours the direct dissolution of the ores in HF for the clean-up operations.

Tantalum minerals with over 70 different chemical compositions have been identified. Those of greatest economic importance are tantalite, microlite,and wodginite; however, it is common practice to name any tantalum-containing mineral concentrate as 'tantalite' primarily because it will be processed for the tantalum values and is sold on that …
