Sillimanite Mining Equipment for Sale

The minerals sillimanite, kyanite and andalusite are all aluminium silicates having the same chemical formula but different crystal structures and physical properties. They form during metamorphism of alumina-rich sediments. Production worldwide is ~250 000 t/year, mostly andalusite from South Africa, the bulk of which is used for manufacture of mullite refractories. Mullite refractories find applications in high-temperature furnaces and kilns.

Sillimanite Mining Operation

The sillimanite minerals are mined mainly in South Africa, USA and France, whereas the major consumers are found in the major iron- and steelproducing areas of the world. Production has declined over the last decade, due mainly to cutbacks in iron and steel production. Most economic deposits of sillimanite minerals can be classified as metamorphogenic and include contact-metamorphic andalusite deposits, stratabound podiform deposits of massive (corundum)-sillimanite and(corundum)-kyanite rocks and stratiform deposits of kyanite quartzites.

Sillimanite can be mined by open pit quarrying or underground mining method based on several different factors, such as location, depth, ore characteristic, geometry, morphology, environment, economics. SBM provide complete series of high performance sillimanite mining equipment for sale.

Sillimanite Mining Equipment for Sale

Open pit mining is the process of extracting sillimanite ore from the ground by digging. Most open pits are designed in a step-like structure, with each step dug deeper into the earth to reach the area to be mined. The goal is to remove the valuable material, but that involves first removing large quantities of rock at the lowest possible price.
