The exploration and mining of Nigerian barite are primarily by artisanal and small-scale miners (ASM) whose operations are characterized by poor productivity. As a result, the quantity and quality of barites produced do not satisfy the nation's oil sector demands and other industries that require the mineral. This situation leads to massive …

Barite is ubiquitous and known to incorporate 226 Ra through the formation of a solid-solution. In U mining mill tailings, barite is one of the dominant sulfate-binding minerals. In such environments, sequential extractions are generally used to identify the U- and 226 Ra-binding phases and their associated reactivity.

The recovery of barite deposits by open-pit surface mining has generated several quarries within the area of study that are several kilometers long and 10-50 m deep. Open cast mining of barite in the study area was carried out without an environmental impact assessment (EIA) study, thereby resulting in poor waste management.
