| This paper describe improvement of Low-grade rutile Rutile is very important mineral for several industrial applications . So, in this work we will discuss the physical and chemical methods which are used to beneficiation of low grade rutile sample (10 Kg ) was collected from Abu Khashaba beach area at the Mediterranean cost ( Fig. 1 ) . The leach process whereby iron coatings around rutile particles is removed by the addition of sulphuric acid at 20 wt% to mineral at 160°C .Then the sample is sent for the physical processes which include up-current classifiers, gravimetric separation, hydraulic separation and magnetic separation . Stereo microscope and XRF analyses were used to study heavy and light mineral fraction .Rutile identification is established and the results at optimum conditions gave a high grade of rutile product which analyzed 95.8 % Ti with 0.8 % Fe, 1.8 % Zr and 0.80 % Nb. | ||
