The mining industry consumes 2%3% of the world''s energy. That''s the same amount of energy used by the entire airline industry. Our sensorbased sorters can reduce that energy consumption by 15%, as well as reduce the amount of water used by three to four cubic meters per ton of ore.
Feldspar ore is the main source of feldspar mineral concentrate or purified feldspar used in the manufacture of various grades of glass and ceramics including highend ceramics and electronicgrade glass fibers. The glass and ceramic industries, in particular, are major consumers of feldspar, accounting for 95% of total consumption.
The Branton Feldspar Mine is near Bryson City, North Carolina.

Plagioclase feldspars are the most common rock forming mineral on earth and form the groundmass of many mafic, felsic, and intermediate rock. Sodium rich plagioclase or albite is present in more felsic rocks and is associated with alkali feldspar, mica, quartz, and many other minerals.
In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase. Glass and ceramics continued to be the major end uses of feldspar.
