Background Artisanal mining of cassiterite is one tedious activity that is done daily. It involves daily extraction of economic mineral deposits through the use of primitive tools like shovel, digger, and spade. The continuous extractive act by these artisanal miners tends not to bother the Government of Nigeria and as such, there is no detailed record …

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.
