Case story

Rare Earth Processing Residue


Processing and refining rare earth minerals results in a waste stream that is required to be managed and stored in an environmentally secure way. Slurry from the refining process is usually dewatered using conventional mechanical dewatering equipment and the dry waste is then disposed in a secure landfill.

As an alternative to mechanical dewatering and conventional waste storage, Geotube® dewatering units was proposed to dewater and store process residue and integrate Geotube® systems into the overall plant process. More than 100 large units of Geotube® dewatering tubes stacked five levels high were installed as part of an integrated plant waste capture program.
