Kyanite ore, a high-alumina mineral, allows body size control and volume stability, high mechanical strength and high fired strength even under load. Resistance to spalling, cracking, warping, chipping, shrinkage and deformation is Kyanite's strengths, allowing faster heating and immediate cooling.
Kyanite Mining: The kyanite quartzite is drilled and blasted; secondary breaking is sometimes done with a hydraulic hammer. The ore is picked up with diesel-powered shovels, loaded into trucks, and hauled to the primary crusher.
The size and exposure of the kyanite quartzite bodies allow open pit mining. The largest deposit is the Gullsteinberget kyanite quartzite in Solør where more than 30,000,000 t of kyanite quartzite is available assuming an open pit depth of 40 m.

Willis Mountain is a monadnock rising from the rolling Piedmont hills of Buckingham County, ia, near the geographic center of the state. It is composed of Kyanite-bearing quartz that weathers more slowly than the surrounding material. The Kyanite Mining Corporation of Dillwyn has mined Willis Mountain long enough to reduce significantly the profile of the mountain.
Kyanite-eclogites are usually the most severely altered (Harte and Kirkley, 1997 ). The geochemical effects are most dramatic for incompatible trace elements but major elements can be affected in some suites also ( Ireland et al., 1994 ), resulting in an increase …
Kyanite is a blue-grey mineral which has a hardness of 5 or 7 depending on the way it is cut. It is recognizable because of its color as well as because of its elongated crystals which look similar to columns. It occurs in the metamorphic rocks schist and gneiss as well as in igneous pegmatites.
This report prepared by the National Occupational Health Survey of Mining presented statistics concerning safety in kyanite facilities (SIC-1459) Three kyanite facilities were surveyed in February, 1988; another site was inactive at the time of the survey. Information on products and conditions to which workers were potentially exposed was provided in tabular form.

Kyanite is a mineral used in refractory, ceramic and porcelain products. Mined ore-grade rock was ground up and floated to separate kyanite from other minerals. The waste rock and tailings were dewatered in ponds and piles and left onsite. Where iron sulfide minerals in the waste are exposed to water and oxygen, acid mine drainage occurs and ...

Kyanite Mining Corp. President Guy Dixon said in a previous interview that "being able to burn natural gas here at Kyanite is something that the company has looked at various times for the better part of 30-40 years. An access point has always been so far away (it's) been completely ridiculous from an economic standpoint."
Kyanite Mining Corp-oration's ore deposits are kyanite quartzites containing 15 to 40 percent kyanite and usually about 5 percent of other minerals such as mica, pyrite and rutile. South Africa is the leading producing country of andalusite, with an estimated 235,000 metric …
