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.Kyanites typical habit is a bladed crystal, although it sometimes occurs as radiating.

Abstract aluminasilica mixtures were prepared by fusing quartz, china clay, fire clay, and alumina in the electric furnace.When alumina is less than 68, crystalline sillimanite 3al2o3.2sio2 with glass is produced.This material is not very resistant to loads at high temperatures because of the early fusion and internal lubricating action of the glass surrounding the crystals.

Kyanite and the related minerals andalusite and sillimanite are anhydrous aluminum silicate polymorphs with the same chemical formula, but with different crystal structures and physical properties.These minerals form during metamorphism of clay-bearing sedimentary rocks or in pegmatites.In the united states, where kyanite is prevalent, these three minerals comprise the kyanite minerals group.
Slightly lower than that of natural sillimanite.The study of grinding kinetics using ball mill indicate that the slope value obtained for thermally treated sillimanite is lower than the natural sillimanite, which shows that the sample responded to higher rate of grinding.
Clusters of sillimanite with pyrite were occasionally observed.The different impurities cause the changes of colour in the quartzite.In the case of iron, fine hematite or magnetite crystals impart a pervasive pink or red colour to the quartzite, whereas iron staining surface coating is observed along fractures and fractured contact zones.
In an average test, 82 of the sillimanite was recovered in concentrates which contained 99 sillimanite and 1.04 total ferric oxide.The concentrates were tested at the electrotechnical.

This is considered by orvana to reflect a potassic alteration event in which all original muscovite was replaced by biotite.The contact between quartz-biotite rock and overlying quartz-muscovite-sillimanite schist is defined by a relatively abrupt change in muscovite content from 20 to trace amounts over a distance of 1-3 meters.
