Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4 ). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or ...

Spiral concentrators (Fig. 5.2.3) are devices to separate different solid components in slurrybased upon a combination of the solid particle density, as well as the particle's hydrodynamic properties (e.g., drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid …

Chromite beneficiation plants generate large amount of tailings with significant amounts of ultrafine chromite minerals. In the present investigation, Box−Behnken experimental design was used to model the effects of feed rate, feed pulp density and splitter position on the performance of a spiral concentrator for separating …

Bauba Platinum has awarded a contract for a chrome spiral circuit wash plant and the primary crushing circuit at its Moeijelijk mine in Limpopo province, South Africa.
