摘要：
A process for dewatering oil sands tailings is provided, comprising providing a tailings feed having a solids content in the range of about 10 wt % to about 45 wt %; adding a flocculant to the tailings feed and mixing the tailings feed and flocculant to form flocs; and centrifuging the flocculated tailings feed to produce a centrate having a solids content of less than about 3 wt % and a cake having a solids content of at least about 50 wt %.
