Introduction. Gravity concentrators utilise the differences in density of minerals in order to facilitate separation. These concentrators may employ natural gravity, or 1 G, such as spirals.In a spiral concentrator, the denser materials flow down along the inner section of the trough, and the less dense material flows along the outer section.
Beach sand material is typically initially concentrated using a cone concentrator to produce a heavy mineral pre-concentrate (20–30% heavy minerals) before a more selective gravity separation step, often employing a spiral concentrator, is used to achieve concentrations of 80–90% heavy minerals (Gupta and Krishnamurthy, 1992).
