Is calamine a carbonate ore?

No, calamine is not a carbonate ore. Calamine, also known as zinc silicate, is a mineral that primarily consists of zinc, silicon, and oxygen. It typically forms as a secondary mineral in the oxidized zones of zinc ore deposits. Calamine is often associated with zinc ores such as sphalerite (zinc sulfide) and is commonly found in combination with other zinc-bearing minerals. Carbonate ores, on the other hand, are minerals or rocks that contain carbonate compounds such as calcite (calcium carbonate) or dolomite (calcium magnesium carbonate). These carbonate ores are a significant source of various elements, including calcium, magnesium, and sometimes zinc, but calamine itself is not classified as a carbonate ore.
