**Step-by-Step Text Solution:** 1. **Understanding the Process**: The question asks for a specific term that describes a process involving the conversion of certain ores, particularly carbonates, into oxides without the presence of air. 2. **Identifying the Ores**: The ores mentioned are primarily carbonates. Carbonate ores are minerals that contain the carbonate ion (CO3) and are commonly found in nature. 3. **Defining the Process**: The process of converting carbonate ores to oxides involves heating the ores. This heating occurs in the absence of air (or oxygen), which is crucial because the presence of air would lead to different reactions. ...
