Feldspars are aluminosilicates. Their fusibility and purity make them a useful raw material with many industrial applications. The geological context specific to each deposit gives the feldspars a variety of physical and chemical properties, thus providing products for a full-range of ceramic and glass-making applications.

Fluorspar or Fluorite has physical properties that allow it to be used for a wide variety of chemical, metallurgical and ceramic processes.
