Ferrous and non-ferrous ores are the two types of metallic minerals (ores). Ferrous ores: These ores have a significant amount of iron in them. Hematite, the most prevalent ferrous ore, is used to manufacture pig iron (a type of steel). Non-ferrous ores: Non-ferrous ores are all those that don't contain iron as a significant component.
