Tailingsfo Thickened Tailings Storage A discussion

Thickened tailings, as the name suggests, involves the mechanical process of dewatering low solids concentrated slurry (Fourie 2003). This is normally achieved by using compression (or high rate) thickeners or a combination of thickeners and filter presses.

High Rate Thickeners Mineral Processing Metallurgy

There are two basic types of high rate thickener units Lamina or tube settlers and solids recirculation units Lamina Thickeners They contain space cutting baffles that intercept settling paths at many levels. Solids settle out onto the baffles and are removed from suspension after settling only a short distance. Where and to the extent that removals
