بيت /microwave technology for iron ore reduction
Heating iron ore fine particles using microwave energy has been effective due to the different interactions between minerals and gangue in the magnetic field generated by the microwave. In this way, this paper proposes to use microwave energy to heat the particles of iron ore to promote micro cracks and fissures, which would facilitate the comminution and pulverization process to produce ...

The thick slag layer separates the ironcarbon melt and char from the oxidizing postcombustion products, providing a medium for heat transfer. The exiting gas is then used to preheat and prereduce the iron ore feed materials. The DIOS process uses a series of fluidized bed reactors for preheating and prereduction of iron ore fines.

'Direct reduction' refers to processes which reduce iron oxides to metallic iron below the melting point of iron. The product of such solid state processes are called direct reduced iron (DRI), whereas the product of the blast furnace is referred to as hot metal in the molten state, or pig iron in the solidified form.

reduction to iron ore. Huanget al. succeeded in reducing iron ore with microwave heating. They reported a design of a microwave smelting ) To the author's knowledge, there are no iron making processes similar to theirs. However, their process employed microwave heating against the reduction from Fe 3O 4 to FeO. Arc plasma was employed

Rusting of iron is a process that involves oxidation and reduction. Oxygen is reduced, while iron is oxidized. While it's easy to identify which species are oxidized and reduced using the "oxygen" definition of oxidation and reduction, it's harder to visualize electrons. One way to do this is to rewrite the reaction as an ionic equation.
