  • Patent number: 10906820
    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.
