Study on Process Mineralogy of a Titanium Magnetite in Ankang Area

The process mineralogy characteristics of a titanomagnetite in Ankang region were studied by means of X-ray fluorescence spectrometry（XRF）,optical microscope,scanning electron microscope（SEM）,X-ray energy spectrum probe（EDS）,etc.The chemical analysis results of the crude ore show that the main elements available for beneficiation and recovery in the ore are titanium and iron,with grade of 20.9% and 7.67% respectively. Mineral identification results show that the mineral types are mainly titanomagnetite（16.8%）,ilmenite（8.81%）,sulfide（1.10%）,gangue minerals（73.29%）. The particle size characteristics of mineral technology show that the particle sizes of useful minerals titanomagnetite,ilmenite and sulfide are mainly in the range of 500 ～ 100 μm,which are closely linked in different forms.Equilibrium of? elements show that the theoretical grade of iron and titanium are 52. 44% and 47. 83%,respectively,and the distribution rates of iron and titanium are 41.65% and 54.30%,respectively. The factors affecting the beneficiation indexes are clarified,which provides a theoretical basis for the formulation of a reasonable beneficiation and metallurgy process.
