Summary

The application of rare-earth permanent magnetic belt/roll separators to minerals processing holds great promise in providing lower cost, higher purity batch materials for the glass industry. This vastly underutilized technology can aid mineral suppliers andglassmakers alike in the development, production, and quality assurance of glassmaking raw materials. In the development of minerals resources, rare-earth magnetic separators can help define the mineral character of a deposit and establish optimum mineral processing methodology. In production, simplified processing schemes and lower operating costs are possible. In quality assurance, assessment of heavy minerals loading and process contamination can be facilitated. The permanent magnetic separator method provides much faster results compared to traditional minerals assessment techniques, saving time and labor costs, while providing accurate answers to a variety of raw material quality question.
