Titanium is a high-demand metal with numerous applications in the aerospace and specialty-product markets. Titanium Dioxide (TiO2) accounts for about 92% of the world’s consumption of titanium minerals, and is widely used as a white pigment because of its brightness and high refractive index. Several conventional processes are currently used for the production of a common TiO2 precursor (synthetic rutile), using either pyro-metallurgical or hydrometallurgical methods. Most of these are limited with respect to titanium-feed grade, capital expenditure, energy consumption, reagent consumption, and/or environmental factors. The Magpie Process is a chloride-based hydrometallurgical process that can produce high-grade synthetic rutile from low-grade ores, which are abundant in Canada but considered unfit for development. The process can be used with advantage for higher grade feeds, and can also use waste products (i.e., tailings and slags) as feedstock to produce high grade synthetic rutile. When compared to conventional methods, the Magpie technology offers considerable economic savings and substantial environmental benefits.
