Again the addition of polymer aids in the separation and thickening process. The disc filter uses vacuum to dewater the magnetite iron ore concentrate and discharges a relatively dry cake which is sent for pelletizing. This process allows ore of very low magnetite content to be processed into a high quality product. Tailings
