The kyanite mineral is a typical aluminum metamorphic rock mineral, which is usually in the form of a layer, which is like stratiformity and has a wide distribution of resources. It includes kyanite, sillimanite and andalusite, which are widely used in the furnace industry of metallurgy, building materials, light industry and chemical industry as a kind of high-quality refractory high-aluminum raw material. The industrialized countries in the world have developed and utilized kyanite minerals for over 70 years. China’s development and utilization of start more
