="ChDivSummary" name="ChDivSummary">Ultrafine barium hexaferrite(BaFe12O19) powders were synthesized from the metallurgical extracts of low-grade Egyptian barite ore via a co-precipitation route. Hydrometallurgical treatment of barite ore was systematically studied to achieve the maximum dissolution efficiency of Fe(99.7%) under the optimum conditions. The hexaferrite precursors were obtained by the co......
