Description
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
