| Summary: | With the samples of the gold-antimony ore processing products of the Sentachan deposit, flotation experiments were carried out on a laboratory centrifugal flotation machine with peripheral concentrate discharge (CFM) and on a laboratory mechanical flotation machine (FM). The selectivity of falling of mineral particles from the flotation mineralized foam flowing along the inclined plane after flotation under different modes (with and without the use of a collector) was investigated; it was shown that the use of a collector can regulate the intensity and selectivity of the falling of material from the foam layer. It was found that the combination of the effect of the centrifugal force of fluid rotation and the hydrophobic properties of minerals makes it possible to enhance the selectivity of the separation of minerals; during flotation in a centrifugal flotation machine, it is possible to carry out cleaning operations in order to improve the quality of the concentrate. |
