Direct Reduced Iron and its Production Processes - IspatGuru

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

Primary Metal Production - Michigan Technological University

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.
