Application of Magstream in mineral sands separation

Magstream separation process has been used as a method for both laboratory and plant mineral separations. It is based on the idea of using a fluid whose effective density is magnetically derived. The separator can be applied to both purely gravimetric separation of non-magnetic materials and magnetic-gravimetric separation of paramagnetic material. A model 100 separator is portable and suitable for analysing small batch samples. It has a selectivity at best ± .1 SG units which may cause a lower grade of products in separation of material with small SG differential. It has been evaluated for mineral sand separations application. Its particularly effective separations were quartz/heavy mineral concentrate, kyanite/zircon, monazite/zircon and rutile/zircon
