Introduction to Mineral Processing or Beneficiation

Jan 12, 2018· In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.

US4189378A - Spiral separators - Google Patents

The helical sluice, or spiral, of a mineral separator used for mineral separation, has a series of take-off openings to carry off strata of dense minerals which form when a pulp of water and minerals to be separated pass through the spiral. Each take-off opening is a slot in the spiral bottom, transverse to the flow, and its effective length, or throat gap, may be varied by a tongue slidably ...

Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.
