Mining industry of Nigeria
Columbite and tantalite are ores used to produce the elements niobium and tantalum. Columbite and tantalite are collectively known as coltan in Africa. Tantalum is a valuable rare element used in electronics manufacturing. In Nigeria, pegmatite deposits of coltan are frequently also the source of several precious and semi-precious stones such as beryl, aquamarine, and tourmaline. These pegmatites are found in Nassarawa State near the Jos Plateau, as well as in several areas in souThe study aimed at investigating the effect of tantalite mining acti The activities of the artisanals and small-scale miners in Nasarawa state, Nigeria, are The impact of tantalite mining on the flora diversity in PubMed
