Recovery of Chromite Values from Plant Tailings by

2013-12-24  The wilfley table is one among the gravity concentration unit operation that separate minerals or other bulk material of different specific gravity by their relative movement in response to gravity and other forces. Usually Wilfley tables are used for the concentration of different heavy minerals such as chromite, iron and beach sand including different plant tailings. The separation performance of Wilfley table depends on both feed characteristics and operating parameters associated with the equipment. Feed characteristics include particle size, density distribution, volumetric flow rate and solid concentration. Similarly the operating parameters include wash water flow rate, deck tilt angle, shake amplitude, shake frequency, splitter position and side tilt angle [3, 5, 6]. Wilfley table

Chromite Sand Separation Plant by SOGEMI foundry

2016-4-13  The chromite is used as facing sand due to its high conductivity of heat that avoids the sintering of the sand in contact with the molten metal and so permit to reach a good surface of the castings. Starting from a mixture in granular size of silica sand and chromite sand, Sogemi plant is able to separate completely the chromite sand from the silica sand.

Chromite - an overview ScienceDirect Topics

However, the general problem with chromite is only found in steel casting operations where it is commonly employed as a facing sand for silica molds. Here the surface of the casting can become coated in so-called ‘chromite glaze’, the result of chromite being fluxed by silica or clay, or simply by the decomposition of chromite as discussed below.
