Overview of realized research on physical processing methods of primary and secondary materials

Abstract

The paper describes research activities of the physical mineral processing group at the Institute of Geotechnics of the Slovak Academy of Sciences in last 5 years. The research programme of this group has been focused on the utilization of ferrofluids in mineral processing, especially in fine-grained materials separation. Other investigation works deal with the possibilities of Slovak brown coal preparation and metallurgical wastes processing as well as with the problems of domestic raw-materials treatment.
