It does appear they confused HPA and SGA. Furthermore, the Canadian Mining Journal excerpt cited by MoneyCristo in his post is incorrect, it should read 3 billion tons and not 3 million tons!!

"For now Boudreault sees the market for Orbite's HPA technology in environmental remediation. The company has already built a production scale HPA plant in Cap Chat, QC. With at 3 million tonnes and more of red mud lying in various stockpiles around the world, the need for clean-up is pressing. But eventually, HPA technology could replace the Bayer process for primary production and the red mud problem would not occur."

 

Good luck to all,
