Feldspar Mineral Processing

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 high-end ceramics and electronic-grade glass fibers. The glass and ceramic industries, in particular, are major consumers of feldspar, accounting for 95% of total consumption.

Igneous Rock Identification

Feldspar (pink to white blocky mineral) crystallizes at high temperatures early in the cooling process and, thus, has straight crystal sides. Quartz (clear, glassy mineral) crystallizes later and fills spaces. Characteristics: Coarse-grained – The grains, or crystals, are big enough to tell what mineral each one is. The crystals are usually
