Copper pyrite or Chalcopyrite is the most common copper ore and a copper iron sulfide mineral. It has the chemical formula (CuFeS_2) and crystallizes in the tetragonal system. It has a brassy to golden yellow colour and a hardness of (3.5) to (4) on the Mohs scale. Its streak is distinguished as green-tinged black.

Pig iron is used in a blast furnace to make steel. Coal gas and oxygen are blown in high-pressure into the molten iron, causing it to melt. This process gets rid of most of the carbon and impurities in the pig iron, leaving behind purer metal. Steel is made by repeatedly heating and cooling this pig iron until it becomes malleable.
