Tailings – Syncrude

Gypsum is currently used as a treatment aid to accelerate FFT consolidation and dewatering in CT and centrifuge tailings operations. Research however has demonstrated the potential to replace gypsum with a waste byproduct from a process in our upgrader which uses lime and calcium oxide to help capture sulphur dioxide gas and minimize air emissions. This solid byproduct, containing calcium sulphite and residual lime, has so far proven to be an effective tailings treatment …
