In another research by Baba et al. (2015), iron content reduction of typical Nigerian talc ore from the Isanlu area of Kogi State was established with a decrease in iron content from 3.75 to 0.36%, though characterized by high activation energy recorded 90.4% efficiency as compared to highly intensive chlorination-cum-leaching process at 800 °C yielding 75% iron removal efficiency (Orosco et al. 2011).

This work is prompted by the fact that this is very limited work in the aqueous chemistry and physico-chemical properties of tantalite ore found in Nigeria. The only one is our work on the hydrochloric acid leaching, Baba et. al [8]. The results obtained indicate that the dissolution reaction is topochemical and is greatly influenced by hydrogen ion [H+] concentration. However, most of the reported works are in the …
