A 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 …

The basics of heavy medium separation can be studied with an Erickson cone and a small sample size. The pilot plant also has a drum separator that is used for pebble-sized materials (75 mm) and a dynamic Dyna Whirlpool separator (DWP) for fine-grained materials (-15 mm). A variety of ferro-silicon fractions are used as medium in separation.
