Abstract:
Purpose.Mineralogical and physico-chemical study conducted on barite wastes from Ain Mimoun deposit (Algeria) aimed at characterizing theses wastes which occupy thousands of hectares in the vicinity of the plant and present a crucial problem for the population and environment.
Methodology. The investigation was carried out by X-Ray Diffractions (XRD), Scanning Electron Microscope (SEM), X-Ray Fluorescence (XRF), Infrared Rays (IR) and microscopy analysis in addition to thin sections analysis.
Findings. On the one hand, the wastes contain the sulfate of barium as a useful mineral with an acceptable grade of 19.7 %, and, on the other hand, they contain associated gangue minerals that are represented by calcite and silica (17 and 46.1 % respectively) in addition to clays as presented by alumina oxide (8.32 %).
Originality. The originality of this research is the characterization of theses wastes with the purpose of confirming their negative effect on the population and environment which poses a crucial problem.
Practical value.The results obtained supplement the information on barite wastes of Ain Mimoun and allow suggesting a suitable enrichment method which will be applied with the aim of obtaining a high-grade barite ore complying with the requirements of consumers.
