Tantalum. Tantalum. Tantalum is extensively used in products that require high reliability in extreme environments. The metal is commonly found in capacitors and super alloys that are applied in many electronics, automotive and aerospace products. More than half of the world's tantalum is mined in Africa, including artisanal mining operations ...
The results were compared to the results obtained by artisanal processing techniques. The proposed mechanized techniques were found to increase the efficiency of tin and tantalum recovery from 60.75% to 81.85% and from 22.9% to 48.57%, respectively, and the grades of the tin and tantalum increased to 63.75% and 35.7%, respectively.
