Mineralogy and geochemistry of geophagic materials from Mashau Village in Limpopo Province, South Africa
Literature indicated that several mineralogical identification studies have been carried out on clays but few have focused on the characterisation of geophagic materials from South Africa. Large quantities of earth materials are consumed daily in Mashau Village, however, their mineral content and …

Biosolubilization of K-silicates in pelitic rock by Acidithiobacillus thiooxidans
… phases were subjected to X-Ray Diffraction (XRD) analysis for mineralogical characterization. In the filtered, pH, redox potential and soluble contents of some elements (K, Al, Fe, Si and S) were measured. In the presence of A. thiooxidans the estimated initial pH of 4.2 was reduced to 0.57 at 49 …
