The trommel undersize was pumped to a sizing screen and the screen undersize was fed to the pre-leach thickener. The screen oversize, previously recycled to the ball mill was subsequently rejected. Almost from the beginning of operation the reject streams exceeded 15% of the feed to the ore preparation plant.

11/ Pre-leach thickener Typically, 80% of the particles in the slurry emerging from the pre-leach thickener are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to "see" the gold in the leaching process.
