Abstract
- In a new process for the production of synthetic rutile, aeration rusting is the major step where metallic iron is converted to iron oxide in the presence of catalysts such as NH 4 Cl and air. An electrochemical investigation to understand the anodic dissolution of reduced ilmenite (RI) has been carried out using a reduced ilmenite carbon paste (CP) electrode at 30 °C. Intermediate products with different iron contents were formed during the rusting reaction. Synthetic rutile with a negligible iron content was used for the investigations. The reaction mechanism and the influence of TiO 2 matrix were studied.
