Studying the possibilities of improving centrifugal separation efficiency

Abstract

Object and aim of research. One direction in improving valuable components extraction in centrifugal separation is to apply it in the scheme of circular concentration. By means of multiple passing of a pulp flow through the centrifugal separator, higher indicators of valuable component extraction in heavy residue are ensured. The aim of this research is to study the possibility of improving the efficiency of centrifugal separation based on float circulation. Methodology. Laboratory testing has been carried out to cope with the given task. Centrifugal separation has been fulfilled in a laboratory fortex formation centrifugal separator K-200VL under the cone rotation 86 "Izvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal". No. 3. 2020 ISSN 0536-1028 frequency of 1000 r/min. Hydrocycloning has been carried out in cyclone separator GTs-75 with the apex diameter of 1.7 cm. The obtained concentrate and tailings were subject to gold assay test. According to the results of the assay test, the calculation of gold extraction in heavy residue and float has been fulfilled. Summary. The obtained result testifies to high efficiency of the proposed technical solution. The proposed technical solution ensures improved efficiency of the process by means of increasing the extraction of particles of increased density in the concentrate when increasing its quality and reducing specific water consumption for the process
