español: :calamina. ; carbonilla.

English: :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 late 18th 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.
