[Solved] Calamine is an ore of:

During the early 19th century it was discovered that what had been thought to be one ore was actually two distinct minerals: Zinc carbonate ZnCO 3 or smithsonite and Zinc silicate Zn 4 Si 2 O 7 (OH) 2 H 2 O or hemimorphite. The term calamine has been historically used to refer to both minerals indiscriminately.
