The results of enriching the products of gold-antimony ore processing using centrifugal flotation are presented. A series of experiments was conducted on a laboratory centrifugal flotation machine with peripheral unloading of concentrate (CFM) and on a laboratory mechanical flotation machine (FM). The selectivity of deposition of mineral particles from the flotation mineralized foam flowing on an inclined plane after flotation under different conditions (with a collector and without the use of a collector) has been studied. It has been shown that it is possible to regulate the intensity and selectivity of deposition of material from the foam layer by using a collector. It is established that the combination of the effect of the centrifugal force of fluid rotation and the hydrophobic properties of minerals makes it possible to strengthen the selectivity of mineral separation, flotation in a centrifugal flotation machine can be used for purification operations with the aim of improving the quality of concentrate.
