Canada’s Argex Mining is pioneering a new process that can extract problematic elements and still produce high quality TiO2

In the wilds of Quebec, Canada, a junior mining company has pioneered a new process for the extraction of titanium dioxide (TiO2) from ilmenite that differs significantly from the existing chloride and sulphate processes.

This new process was developed by Canada Titanium Ltd (CTL) which was purchased in October 2011 by Argex Mining Inc.

Argex is a junior mining company with two titanium properties - La Blache and Lac Brule - as well as an iron property it is exploiting through a subsidiary.

La Blache is lower grade of TiO2 and closest to production, while Lac Brule is of a higher grade and has previous NI 43-101 work done on it but is further from production.

CTL granted Argex an exclusive licence in the province of Quebec and a non-exclusive licence for the rest of the world to use the process.
