The decomposition of ilmenite slag by ammonium hydroxide was investigated as a potential enhancement to produce high-purity titanium oxide. It was discovered that the powdered ilmenite slag broke down when it was digested in 4 M NH₄OH at 150 °C. Ammonium titanate ((NH₄)₂TiO₃) was created, and this material was easily hydrolysed in hot water to produce high-purity rutile (TiO₂). It can be determined that it is in the rutile phase using X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM-EDX), and other analytical techniques. A flow sheet was created and tested in accordance with the experimental findings. Present study we focus on conversion of waste ilmenite mud produced from VV titanium pigment private limited Thuthukudi. Ilmenite mud generated during production of TiO₂ through H₂SO₄ digestion. Unreacted mass of ilmenite basically comprised of acidic resistive TiO₂ phases such as rutile and anatase. Other mineral mainly silicates (SiO₂, ZrSiO₄). This study is primarily focused on the reutilization of secondary waste generated from TiO₂ production, aiming to recover valuable elements while ensuring the production of zero secondary waste. Ammonia based technology gaining importance due to the factor like high selectivity of transitional ammonia complex, recyclability of ammonia and low temperature reactions. In this we aimed to lower the production cost of TiO₂ from secondary resources
