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.
