This type of thickener features a fabricated sag steel floor on larger diameter tanks and provides open access under the tank for more ...
The leach tanks are designed to provide a residence time of four hours each, for a total leach time of 24 hours. Milk-of-lime ("MOL") is added to slurry at the pre-leach thickener feed while sodium cyanide is added to the leach feed splitter box with stage addition of either into the leach tanks as required.
The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed mass, rake torque, rake height, solids settling rate and underflow rehology.

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.
