On this premise, the mineral ore is initially screened using the wet plant before being taken to the hydrocyclone bank in order to eliminate the slimes (very finer mineral particles). These slimes will become thickened and thus will re-mix with the tailings of quartz sand minerals, then pumped up to the mine area for containment.
