उत्तर
Pig iron
Explanation:
An ore is a naturally occurring mineral from which a metal can be extracted profitably. Bauxite, Malachite, and Zinc blende are all ores: Bauxite is an ore of aluminium, Malachite is an ore of copper, and Zinc blende (ZnS) is an ore of zinc. Pig iron, however, is not an ore; it is an intermediate product obtained by smelting iron ore in a blast furnace. It is a form of impure iron, not a naturally occurring ore.
