A seat removal tool is disclosed for removing valve seats. A seat removal tool having a main rod, actuator rod within the main rod that actuates to cause radially expandable extraction segments to transition between an expanded position and a contracted position. When using the seat removal tool to remove a valve seat, portions of the radially expandable extraction segments may pass through a seat while the valve seat removal tool is in a contracted position. Thereafter, the seat removal tool may transition from the contracted position to an extended position, which grabs the seat. While in the expanded position, the seat removal tool may pull the valve seat from the passage.

The present invention relates to methods for dewatering tailings and systems for performing same. In certain aspects, the invention relates to methods of producing a dewatered tailings residue or a stackable tailings residue, comprising subjecting tailings to hydrocyclonic separation to produce one or more partially dewatered underflows and a final water-rich overflow; separating the final water-rich overflow, by centrifuging, into a recovered water stream and a low-water residue; and mixing together the low-water residue and at least part of the one or more partially dewatered underflows to produce a dewatered tailings residue or a stackable tailings residue.
