The main ore sources for the production of tantalum and niobium include pyrochlore, microlite, tantalite, columbite, and columbo-tantalite . Besides, some smelting slags (such as tin slag [4,5,6,7], iron slag, tungsten slag, etc.) and tantalum–niobium tailings are also important raw materials for tantalum–niobium manufacture. Most tantalum ...

Nigeria has been among the major producers of columbite, alongside other minerals such as tin and coal. Today, it accounts for up to 95% of the world's output. And up till the present time, the mining and exploration of columbite in Nigeria have made it one of the highly important strategic minerals occurring in the country.

Columbite concentrates and tin slags with a high tantalum content (greater than 10 percent) are directly dressed in most cases by a wet chemical process. Low-tantalum tin slags, on the other hand, are first melted in an electric-arc furnace with the addition of a flux material, and the tantalum-niobium content is collected as a ferroalloy .

Tin mining activities in Nigeria started in 1904 at the Jos Plateau (Fig. 1) By the mid-1920s more cassiterite and columbite discoveries were made resulting in a greater demand for more mechanized extraction techniques. This resulted in the removal of considerable amounts of soils and generated radioactive waste referred to as tailings.
