Tin and Columbite mining in Nigeria
Columbite Mining: Columbite mining refers to the extraction of columbite-tantalite ore, also known as coltan. Columbite is a black, metallic mineral that contains both niobium and tantalum elements. Tantalum is particularly valuable due to its high melting point, corrosion resistance, and ability to store and release electrical charge, making ...
