Calamine est une appellation désuète qui peut désigner l'hémimorphite ou la smithsonite, mais aussi d'autres minéraux de néoformation des fourneaux (oxydes de zinc). Toutefois on parle encore en botanique de flore calaminaire.Jusqu'au XVIIIe siècle, la calamine était une source essentielle pour la production de laiton, car le zinc métallique n'existe pas dans la nature et aucune technique n'était connue pour le produire.

For calamine used in calamine lotion, see calamine, for other uses of the word, see calamine (disambiguation).Calamine is a historic name for an ore of zinc. The name calamine was derived from the Belgian town of Kelmis, whose French name is "La Calamine", which is home to a zinc mine. In the 18th and 19th century large ore mines could be found near the German village of Breinigerberg.During the early 19th century it was discovered that what had been thought to be one ore was actually two distinct minerals: Zinc carbonate ZnCO3 or smithsonite and Zinc silicate Zn4Si2O7(OH)2·H2O or hemimorphite.The two minerals are usually very similar in appearance and can usually only be distinguished though laboratory analysis.The first person to separate the minerals was the British chemist and mineralogist James Smithson in 1803. In the mining industry the term calamine is still used to refer to both minerals indiscriminately.In mineralogy calamine is no longer considered a valid term. It has been replaced by smithsonite and hemimorphite in order to distinguish it from the pinkish mixture of zinc oxide (ZnO) and iron(III) oxide (Fe2O3) used in calamine lotion.Until the 18th century, calamine was essential for the production of brass since metallic zinc does not exist in nature and no technique was known to produce it. Brass produced using calamine is called calamine brass.
  • Calamina é o nome comum para o minério de zinco. Até o século XVIII, acreditava-se que era um único mineral. Esta designação abrangia três minerais distintos: smithsonita, hidrozincita e hemimorfita. Estes minerais podem ser muito similares na aparência e somente ser identificados completamente através de análise química. O primeiro a separar os dois minerais foi o químico e mineralogista britânico James Smithson, em 1803. Na indústria de mineração, o termo calamina é usado ainda para descrever, indiscriminadamente, os vários minerais de zinco. No entanto, em mineralogia esta designação deixou de ser considerada válida, apesar das tentativas de restringir o nome calamina a um dos minerais, porém sem sucesso. Para os mineralogistas estado-unidenses, e franceses calamina era o silicato de zinco e smithsonita o carbonato de zinco. para os mineralogistas britânicos, por outro lado, o carbonato de zinco era a calamina. Hoje em dia, a smithsonita é o carbonato de zinco, a hemimorfita o silicato de zinco e a hidrozincite é um carbonato hidratado de zinco.
