What is Kyanite? Kyanite is a mineral found mainly in metamorphic rocks.It most often forms from the high-pressure alteration of clay minerals during the metamorphism of sedimentary rocks.It is found in the schists and gneisses of regionally metamorphosed areas and less often in quartzite or eclogite.. Kyanite's typical habit is a bladed crystal, …

Geological Occurrence Crustal abundance is approximately 1.5ppm. Present in many lead–zinc and copper ores, most commonly in the mineral arsenopyrite. It is also common in orogenic gold systems where arsenic minerals, along with pyrite, often host gold in refractory gold ores. Mineral system group Mesothermal and epithermal veins.
Clays that contain as much as 1% lithium may be common enough in Missouri or in Pennsylvania to be produced as a by-product to help support benefication costs for refractory clays. Sufficient amounts of lithium-rich clay may be found in deposits that have been explored, found unsatisfactory for normal refractory uses, and not developed.
In fact, the performance of a refractory (good resistance to heat and thermal shock) is directly related to texture and richness of the mineral refractories, such as …
