Metal ores are generally oxides, sulfides, silicates (Table 12.3. 1) or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust, or "noble" metals (not usually forming compounds) such as gold (Figure 12.3. 1 ). The ores must be processed to extract the metals of interest from the waste rock and from the ...

The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O 2) in the air to produce carbon monoxide (CO). Second, the carbon monoxide reacts with the ore (e.g. Fe 2 O 3) and removes one of its oxygen atoms, releasing carbon dioxide (CO 2).
