Systems and methods for separating mine tailings from water-absorbing polymers and regenerating the separated water-absorbing polymers. The systems and methods include a separation assembly that is configured to receive an augmented mine tailings slurry that includes mine tailings, water, and a swollen water-absorbing polymer. The separation assembly separates the swollen water-absorbing polymer from the augmented mine tailings slurry to produce a dewatered mine tailings slurry. The systems and methods further include a water-absorbing polymer regeneration unit that is configured to receive the swollen water-absorbing polymer. The water-absorbing polymer regeneration unit at least partially releases water from the swollen water-absorbing polymer to produce a regenerated water-absorbing polymer, and as a separate output or product, the released water.
