This research is devoted to the study of the extraction of zirconium from Iraqi Bauxite Ore by using hydrometallurgical method.
The chemical analysis was done to the bauxite ore by using X-ray florescence, X-ray diffraction and atomic orption spectroscopy.
Zirconium Extraction was performed via three stages; the first stage is leaching of bauxite with sodium hydroxide for alumina leaching.
The second stage is leaching of zirconium species from the remained powder produced from stage one after washing with deionized water and, nitric acid (HNO3 solutions).
The results of the first stage has reflected the recovery of 42.27 % of Al2O3 which has been leached 100°C temperature, 7.5 molar of NaOH, liquid to solid ratioof 20/1, and stirring rate 450 rpm.
The highest leaching percent of zirconium (Zr% ) from the red mud approached 98.48 % at 100°C temperature, 7 molar acid concentration, 120 min.
contact time, solid to liquid ratio(S/L) of 16/1, and stirring rate of 450 rpm.
99.47% recovery of zirconium was accomplished from nitric acid solutions byuse of 3molar tri-n-butylephosphate (TBP)in kerosene at, contact time for 6 min, and organic to aqueous phase (O/A) of X-ray diffraction and atomic orption spectroscopy.
