THEORETICAL ANALYSIS OF THE TECHNOLOGY FOR SEPARATION OF IRON OXIDES FROM BASALT USED AS A FILLER FOR POLYVINYLCHLORIDE

Abstract

Currently, significant scientific research is being conducted on the use of basalt ore as a filler for polymer materials. The advantage of basalt compared to other fillers lies in its complex multi-component composition, which contributes to improving the physical and mechanical properties of polymers. This makes it possible to replace imported fillers with locally available basalt resources, thereby reducing production costs and increasing the utilization of domestic raw materials. However, before basalt can be used as a filler, it must undergo several stages of mechanical processing, including crushing, grinding, and classification. In addition, purification from certain metal oxides is required, which can be effectively achieved using magnetic separation methods. Magnetic separators enable the removal of ferromagnetic impurities, improving the quality and performance of the final polymer composite material.
