12.3: Metals and Ores
Metal ores are generally oxides, sulfides, silicates (Table (PageIndex{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 (PageIndex{1})). The ores must be processed to extract the metals of interest from the waste ...
