Beneficiation for the Family of Kyanite Minerals

The family of kyanite minerals-kyanite, sillimanite and anda-lusite, arc excellent high - temperature swelling type refractories. This article introduces their properties, uses and industrial requirements for product quality , as well as distribution of the principal mineral deposits at home and abroad, their types and characteristics. Based on a number of mineral processing experiments and production practice, describes the main mineral processing techniques for treatment of various kyanite types, also deals with separation results by use of g ravity- magnetic, gravity-flotation and gravity - magnet ic-flowsheets.
