A detailed study was carried out for selective removal of iron oxide (Fe2O3) from low grade ferroginous bauxite using hydrochloric acid leaching in order to enrich it and make it suitable for manufacture of refractories and abrasives optimum process conditions like leaching temperature, solid/liquid ratio (W/V) of slurry, leaching time and strength of hydrochloric acid solution. The alumina (Fe2O3) content of the enriched bauxite has been improved from 36.12 to 77.7% after removal of iron oxide (over 81% yield)
