Hydrogen Plasma Processing of Iron Ore SpringerLink

Mar 16, 2017 · Iron is currently produced by carbothermic reduction of oxide ores. This is a multiple-stage process that requires large-scale equipment and high capital investment, and produces large amounts of CO2. An alternative to carbothermic reduction is reduction using a hydrogen plasma, which comprises vibrationally excited molecular, atomic, and ionic states of hydrogen, all of which can reduce iron

Smelting Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Understanding US iron ore production CRU

The cost of getting iron ore in and out of the Great Lakes is simply too high for any major trade to take place with the rest of the world. Therefore, the USA remains a very marginal player in the seaborne iron ore market. In 2019, seaborne iron ore exports are expected to be ~3 Mt, which accounts for ~0.2% of global seaborne trade.
