ABSTRACT
This research is concerned with analysis of ore chromite samples from the Blue Nile region. The samples were treated, powdered then subjected to a non-destructive XRF analysis to determine the elemental species. The level of elemental species was found to be Magnesium oxide (17%), Aluminium oxide (7%),ferrous oxide (15%), chromium oxide (50.18%) silicon oxide (9%).
The samples were then fused at 1000 °C in the presence of sodium carbonate then dissolved in distilled water. In this process, the trivalent chromium was converted to hexavalent species, which was then determined using simple classical volumetric technique.
