Chalcopyrite is an important ore of copper found in a wide range of hydrothermal environments. It is often associated with sphalerite and galena. It oxidizes to form copper minerals such as malachite, azurite, cuprite and tenorite. Copper liberated from the breakdown of chalcopyrite may accumulate in secondary supergene enrichment zones, …

The effect of the temperature used in roasting chalcopyrite with lime was determined first. A range of 600° to 900° C was selected for testing after it was found that below 600° C, CaSO3 was formed, while above 900° C, CaSO4 decomposed to CaO plus SO3. This is in agreement with the findings of other investigators.
