The recovery and separation of heavy minerals of natural raw materials or as a by-product of the silica sand processing. Special processes guarantie the recovery and the separation of contaminating minerals even in very small amounts.

Classification, attrition and gravity separation for pre-concentration will be followed by different kind of magnetic separation techniques, gravity separation, electrostatic separation and in case thermal treatment.

Dr. Jakobs GmbH do has a high competence in processing of Chromite, Barite, Rutil, Ilmenite and others.
