Hemimorphite is a chemical compound represented by the formula Zn4(Si2O7)(OH)2·H2O and is a constituent of the mineral calamine. This silicate mineral, along with smithsonite (ZnCO3), has been historically extracted from the upper regions of zinc and lead ores. Initially, both minerals were thought to be identical and categorized under the name calamine. However, in the latter part of the 18th century, it was determined that these distinct compounds coexist within calamine, despite their close resemblance.
