Orbite Aluminae enters into partnership to deal with red mud problem
TORONTO (miningweekly.com) – Canadian alumina producer Orbite Aluminae and Veolia Environmental Services on Monday said the companies had entered into a global collaborative agreement for the treatment and recycling of red mud generated by industrial alumina production using the Bayer process.
Under the partnership, a new plant to treat the red mud using Orbite’s patented process would be constructed.
Red mud is a caustic waste that is difficult to treat owing to existing purification processes being complicated, costly and ineffective. Red mud often remains stored on site, which increases the risk of accidental spills.
To meet this complex industrial and environmental challenge facing the aluminium industry, Orbite and Veolia would attempt to roll out the solution to treat red mud to stockpiles around the world in an economically and socially sustainable manner. The Orbite process is the only proven and commercially viable eco-friendly technology for treating Bayer process tailings and it recovers their entire commercial value and could even extend the life span of Bayer plants.
Orbite’s technologies allow for the extraction of smelter-grade alumina and high-purity alumina, as well as other products such as rare earths and rare metals from various feedstocks, including aluminous clay and bauxite, all without producing red mud.
“Demand for alumina continues to grow on a global scale and worldwide stocks of untreated red mud are estimated at nearly three-billion tons,” Orbite CEO Richard Boudreault said.
