  • what is the process for the mining of sillimanite

    Sillimanite, kyanite and andalusite - energymining.sa.gov.au. Small and intermittent production of sillimanite and kyanite has been recorded from the Williamstown kaolin deposits, 40 km northeast of Adelaide. These represent areas within the orebody that have not been highly altered to kaolin, and are removed during the initial screening process.

    The association of sillimanite and either andalusite or kyanite appears to represent disequilibrium; textural evidence in general suggests that the sillimanite is of later formation than the other aluminium silicates and resulted from a localised temperature rise subsequent to the imposition of an equilibrium pattern of andalusite and kyanite.

  • Kyanite And Related Minerals

    The sillimanite family of minerals, including kyanite, sillimanite, and andalusite, are anhydrous aluminum silicates with the formula A12O3-SiO2. Dumortierite and topaz are also included in this group because they are closely allied in composition and thermal behavior. However, neither are mined commercially today.
