Effect of Wash Water on the Mineral Size Recovery Curves in a Spiral
In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium‐to‐iron ratio.The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron Improving the Quality of Ferruginous Chromite Concentrates

Chromite ore is geologically associated with gangue materials which have lower density compared to pure chromite (FeO.Cr2O3). Gravity separation techniques are very suitable for beneficiation ofA gravity concentrator namely “vibrating table” has been developed with the objective of increasing the product quality of density based physical separation processes. The system is mainly composed of a vibration unit, an inclined chute, TW and WW jets. The principle idea of the separation is to combine the involved forces of a A new method for gravity separation: Vibrating table gravity

WASH WATER OPTIMIZATION ON AN IRON ORE SPIRAL Multotec
Separation on a spiral is achieved through a combination of forces that act on particles as they move down the trough of the spiral. The main forces known to act on the particle on a spiral are the gravitational forces, centrifugal force, hydrodynamic drag, and lift and friction forces (Kapur & Meloy, 1998).was further beneficiated using the spiral concentrator. The results obtained showed that the removal of fines increased the Cr 2 O 3 grade for the spiral feed from 12.27% to 17.64% while spiral concentrate grade improved from 14.84% to 21.46% and recovery 69.85% to 95.53%.
