Water plays a vital role in mineral processing and about 2-3 tons of water is used for the treatment of one ton of ore. The objective of water recovery in thickener is to increase the solids concentration at the underflow to obtain clear water at the overflow.

At the beginning the processing of metalliferous ores consisted of their size reduction by manual crushing. As technology progressed the manual (and later mechanised) selection of valuable minerals for obtaining from them concentrates, suitable for the following pyro (and later hydro) metallurgy, was introduced.

These include the pre-concentration performance evaluation, correlation between the breakage mode-based separation and the size-based separation, the interaction of multiple metalliferous minerals, and the pulse energy transfer efficiency. The technique may have a potential to be applied for other mineral ores.

The process for obtaining lithium from spodumene consists of concentrating up to 3% lithium by flotation. Because other minerals associated with this mineral are mainly silicates (feldspar, clays, quartz and micas), great problems are generated in the thickening stage.
