Abstract
The research data on the finishing centrifugal flotation of the pre-concentrated gold-antimony ore product are reported on a series of laboratory tests at a centrifugal flotation machine with peripherical discharge of the concentrate (CFM) and a mechanical flotation machine (FM). The selectivity of mineral particle detachment from the mineralized flotation froth moving along an inclined plane after flotation process running at different modes with/without a collector. It is demonstrated that the use of a collector makes it possible to control intensity and selectivity of material detachment from the froth layer. It is found that flotation finishing in the centrifugal flotation machine actually enables to improve the final concentrate characteristics.
