English abstract

In numerous cases of mineral processing, fine to ultrafine mineral particles are inevitably produced during the process of mineral liberation, with the percentage depending on the ore-grade. In case of low-grade ore, efficient liberation demands excessive grinding, as a necessity for efficient separation of fine-grained mineral value from gangue. Due to the peculiar properties of fine particles (physical, chemi- cal), conventional processing methods have limited success or fail to separate the particles, especially at industrial level, because of the concomitant problems. As a result, mineral values of many commodities are lost to the tailings, e.g. phosphate, copper, tungsten, tin, sulfide minerals, iron, etc. With mining operations been shifted to the exploitation of even lower-grade ores, the problem of fine particles separation is expected to deteriorate. The current paper deals with the innovation in equipment and processes devel- oped to meet the problem of fine/ultrafine particles separation. Special emphasis is placed on physicochemical methods, which are mainly based on the improvement or modification of already known ones.
