This study focusses on upgrading Sri Lankan ilmenite sands to synthetic rutile via a mechanochemical method. Ball milling-induced sulphurisation and carbothermic reductions were examined using several geochemical techniques. Raw ilmenite concentrate contained over 95 wt% FeTiO 3, ∼2 wt% SiO 2, and ∼ 1 wt% Al 2 O 3.

The deposit is execute-ready and off-take arrangements are currently being sought. When operational, it is estimated the deposit will produce around 380 kt of ilmenite, 30 kt rutile and 50 kt zircon annually. The ilmenite will be used as a feed source for Iluka's Synthetic Rutile kiln 2 in southwest Western Australia.

Wet Milling Process Custom Milling Consulting. Wet milling, also called wet media milling, is a process in which particles are dispersed in a liquid by shearing, by impact or crushing, or by attrition. A mill is charged with media small beads or spheres and activated by a high speed agitator shaft to separate the individual particles. Read More

However, the main drawback of Ti 2 AlC—as with Ti 3 AlC 2 —is the oxidation of the "M" element at temperatures as low as 600°C, forming rutile (TiO 2). As temperature increases the oxidation of the "A" element is favored, leading to the formation of an alumina scale that controls the oxidation kinetics.

Fig. 1 displays the PSD of the nonactivated and activated samples under three milling modes as a function of the milling time. The P 80 of the nonactivated sample was 66.9 μm, and the particle sizes decreased rapidly for all three milling modes. After 1 h of milling, the P 80 decreased to 8.72, 6.42, and 16.71 μm in the DM, MM, and WM modes, respectively.
