Forecasting preliminary mechanical activation effect on arizonite and ilmenite concentrates by X-ray crystal analysis

It is possible to forecast variation in energy content and reactivity of arizonite and ilmenite concentrates after their mechanical activation using data of X-ray crystal analysis. It is found that energy of arizonite and ilmenite after mechanical activation differs from energy of structural damages within the minerals. Effect of the energy, accumulated in the course of mechanical activation in the form of the surface energy and micro-strains, on the subsequent leaching process has been proved. The efficient preliminary mechanical activation of arizonite and ilmenite makes the background for manufacturing of artificial rutile from available mineral raw material.
