A typical slimes processing route in a heavy minerals operation is to separate the slimes from the rest of the ROM by using hydrocyclones. The slimes would then report to the hydrocyclone overflow and further processed in a thickener. Very fine particles of a few microns in diameter settle slowly by gravity alone (Wills, 2007, Hayes, 2003).
