| 释义 | > as lemmaselectric calamine An ore of zinc: originally applied, like medieval Latin lapis calaminaris, and the cadmia of Pliny, to both the carbonate ZnCO3, and the hydrous silicate Zn2SiO4, H2O but chiefly, in France and England, to the former, which is an abundant and important English ore of zinc. The silicate, found in Carinthia, Hungary, Belgium, New Jersey, etc., is distinguished as siliceous calamine or electric calamine.The chemical difference between the two ores was established by Smithson in 1802; in 1807 Brongniart unfortunately chose calamine as the mineralogical name of the silicate, leaving the other ore as zinc carbonatée, which Beudant in 1832 named smithsonite n. This nomenclature is followed by Dana. But common English and French use (see Littré) continued to apply the name calamine to the carbonate; and in conformity with this Brooke and Miller in 1852 reversed Beudant's use of calamine and smithsonite. With British mineralogists, chemists, miners, and manufacturers, calamine therefore means the carbonate.
