Colemanite or hydrated calcium borate (Ca2B6O11.5H2O) is a colorless or white monoclinic crystal which formed by the evaporation  of deposits together with other borates. Colemanite is a secondary mineral which derived from borax and ulexite. Colemanite is a common natural source of insoluble boron and also one of the more stable borate mineral. 

Production process:

Colemanite is enriched via crushing, wetting in water, washing in a thumbling, sieving, triage and classification. Colemanite forms at a lower pH and warmer temperature than other borates.

Application:

Colemanite is a significant ore of boron and was the most impoertant ore prior to the discovery of Kernita in 1926.
