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 …
Mining Company, and Midrock, Ezana Mining Development Plc. EMDSC is carrying out both mining and processing of tantalite ore at Kenticha and exporting the tantalite concentrate. At present, Kenticha Ta deposit is the only mineable tantalite deposit in the country. Tantalite ore has been mined using open pit mining method since 1991.
