Kopanytsa Y. Separating reject waters from the enrichment plants in the pressurizing hydrocyclones with the pneumatic regulation

The results of theoretical and experimental studies of the process of thickening rejects flotation in the pressurizing hydrocyclones with the pneumatic regulation are illustrated. The obtained results enabled us to propose more advanced technology of stabilizing vacuum-filter supply along the whole diapason of the output parameters (the pressure and pulp thickness) at the entrance of the hydrocyclones. This enable to im-prove the quality of the cleaning process of the reject waters, which is used in the system of reversed supply of the water to enrichment plant. The engineering cal-culation method of the technological parameters for the process of thickening rejects waters in the hydrocyclones and design parameters of the industrial pneumatic regulator with the indicator of the optimal regime of the of the equipment operation of the whole water-reject system has been developed.
