For the metallurgical process of which of the ores calcined ore can be reduced by carbon?

In the metallurgical process, the oxide ores are reduced by carbon. Sulphide ore cannot be reduced by carbon. Here, haematite (Fe2O3) and calamine (ZnO) are oxide ores of iron and zinc respectively while iron pyrites (FeS2) and sphalerite (ZnS) are sulphide ores of iron and zinc respectively. Therefore, haematite and calamine can be reduced bycarbon.
