Mineral processing - Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

Especially the initial processing step requires temperatures of up to 1000 °C. An accumulation of the spodumene by reduction of the waste rock content in the initial feed is therefore crucial for the optimisation of energy and chemicals consumption during the process. Common minerals accompanying spodumene in deposits are feldspars and quartz.

To obtain minerals suitable for age-dating and other analyses, it is necessary to first reduce the mineral-bearing rock to a fine, sand-like consistency. Reducing whole rock requires crushing, grinding, and sieving. Ideally, the reduced material should range in size from 80- to 270-mesh (an opening between wires in a sieve). The openings in an 80-mesh sieve are equal to 0.007 inches, 0.177 ...
