Investigation of Silicon Cyclone Dust and Products of Its Flotation Enrichment

This article presents the X-ray fluorescence and X-ray diffraction analysis results and the granulometric composition of silicon production cyclone dust and its flotation enrichment products. The technology used for the preliminary preparation of cyclone dust before flotation enrichment is presented. The process of fine media flotation should include the careful preparation and reliminary processing of raw materials, otherwise it is difficult to achieve high flotation selectivity. Technological preparation necessarily includes the following stages: preliminary preparation of dust for flotation; repulping of prepared dust; sonochemical treatment of pulp; gravitational separation of sand phase; flotation separation. A structural diagram of the flotation separation technology used for the silicate and carbon phases of cyclone dust has been developed. As a result of this research, the characteristics of cyclone dust have been obtained, allowing us to draw conclusions about the possibility of its flotation processing and further use of the obtained products in the construction industry. The results of a study of carbon in a froth product have also been obtained. Carbon nanotubes have been discovered.
