Gold Cyanidation Process
Assuming an ore where the solids have a specific gravity of 2.6, one ton of solids as 30% solids (70% solution) will occupy 86.7 cubic feet, while at 50% solids will only occupy about half that space, namely, 44.31 cubic feet. ... Thickening. Thickening may be defined as the mechanical process whereby excess solution is removed from a pulp ...
Tailings Management With Paste Thickening
The desliming prepares the ore for flotation, discarding the ultrafine particles. The underflow from the desliming thickener is sent to a series of finisher magnetic separators to further purify the solution. The overflow from this thickener reports to the tailings thickener.
