Nepheline Syenite Beneficiation for Glass and Ceramics Industries

Abstract

This study aims to treat Nepheline syenite for the glass and ceramics industries. Nepheline syenite has many uses in the glass and ceramics industries. It uses to lower the melting point and fuel savings. In the glass industry, nepheline syenite acts as a source of alumina, which increases resistance to scratching and breaking, improves thermal endurance, and increases chemical durability. A series of processing methods such as dry magnetic separation, flotation, and leaching methods were used respectively to treat nepheline syenite ore. In this paper, the results of combined magnetic, flotation, and leaching Processes of the cleaner concentrate having 0.1% Fe₂O₃ and 23.25% Al₂O₃.
