How Pig Iron is Converted into Iron and Steel in Blast

Iron ore exists as an aggregate of iron-bearing minerals. These mineral aggregates are oxides of iron called hematite, limonite, and magnetite. They all contribute to the smelting process. Hematite is a red ore and contains about 70% iron. Limonite is a hydrated oxide and contains about 60% iron.

Primary Metal Production Michigan Technological

Molten metals tend to dissolve impurities from the ore. For example, many ores that contain native copper have arsenic compounds associated with them. When the ore is melted, the molten copper dissolves the arsenic. As a result, the metal from the furnace can be less pure than the individual metal grains that were originally in the ground.
