History of boron production and processing.
Indus Minerals London J 1992 Dec; (303):19, 21, 22, 24-25, 27, 30, 31, 33, 34, 37
Boron minerals have been mined since the seventh century for use in glass and metallurgy. In addition, boron compounds and boric acid have been produced from brines associated with volcanic activity and salars. Different mineral compounds and different end uses require variations in the mineral processing. In addition, there are variable end uses of the compound or mineral. For example, glass processing can use borax, ulexite, colemanite, or boric acid. The paper discusses various locations of minerals and the processes by which the mineral was or could be processed. Locations include China, India, South America (Argentina, Bolivia, Chile, and Peru), the United States, and the U.S.S.R.; different minerals, such as colemanite, szaibelyite, ulexite, tincal, probertite, and their usage would be discussed. The processes include evaporation, precipitation, carbonation, solvent extraction, flotation, solution mining, and air classification.
