QUEBEC – Orbite Aluminae of Montreal has reached an agreement with the firm M&K of St. Louis, MO, for the engineering and construction of a separation plant capable of producing gallium oxide at a purity of 99.99% and scandium oxide at a purity of 99%+ from the acid recovery circuit of its HPA (high pressure acid) plant in Cap-Chat. The company previously anticipated that the separation and production of these two oxides would begin with the smelter grade alumina (SGA) plant. The separation facility, which had already been designed as part of the SGA plant, will now be integrated into the HPA design, thus advancing the production of gallium and scandium into 2013.
Construction of the HPA plant is ahead of schedule, with commissioning expected to begin in the next few weeks and completion by the end of 2012. The civil engineering and infrastructure work is now more than 98% complete, while the electrical work is also ahead of the original construction timetable.
A series of white papers detailing the technology and potential applications to different markets are available on our website (OrbiteAluminae.com/en/technology/white-paper).
