Innovation at RTIT Quebec Operations

Throughout our history, we have continually improved the processes at RTIT Quebec Operations. After first pioneering a new technique for processing ilmenite, we took on the challenge of diversifying our product line as RTIT Quebec Operations targeted the metal powder and steel markets.

Several technological breakthroughs then sharpened the competitive edge of our products. In the last decade, we have focused on developing, marketing and fine-tuning the UGS process, which produces slag with a very high titanium dioxide content. By developing UGS™, an enriched titanium slag sold to pigment producers that use the chloride process, and RTCS (Rio Tinto chloride slag) a slag made from Madagascar mineral sand, RTIT Quebec Operations have secured a strong position in a flourishing market.

The founding of our Technology and Critical Minerals Centre in 1967 underlined the strategic role that research and development plays and their mission is to develop and improve processes and build the value of our products to expand our markets. Our team of specialists in a wide range of fields of science and technology is a key strength for our business. Today, RTIT Quebec Operations are among the 100 most active Canadian companies in research and development.
