methods of mining of tantalite in nigeria

COLUMBITE-TANTALITE {COLTAN} MINING IN NIGERIA;

2016-3-2  Columbite, also called niobite, niobite-tantalite and columbate, is a black mineral group that is an ore of niobium and tantalum. It has a submetallic luster and a high density and is a niobate of iron and manganese, containing tantalate of iron. Columbite and tantalite are collectively known as coltan in Africa.
