Abstract
A method and system for separating a suspension into solid and fluid components. The suspension is centrifuged about a substantially vertical axis of rotation to concentrate solid components in a first lower flow stream and fluid components in a first upper flow stream. The first upper flow stream may be centrifuged about a substantially vertical axis of rotation to concentrate solid components in a second lower flow stream and fluid components in a second upper flow stream. The first lower flow stream, the second lower flow stream, or both, may be centrifuged about a substantially horizontal axis of rotation to separate water from stackable dry tailings. The method and system may be applied to separation of tailings or other suspensions.
Claims32
A method of separating fines from tailings comprising:
- providing tailings;
- acidifying the tailings;
- and
- centrifuging the tailings about a substantially vertical axis of rotation to separate the tailings into a first upper flow stream comprising water and ultrafines, and a first lower flow stream comprising water and fines.
