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.
