Answer (1 of 2): Calcination or "roasting" is not intended for the oxide ores. Fe2O3 is already in a high oxidation state [Fe(III)], and it is not easy to oxidize it further. Ores are rarely a single compound. Even when you are trying to mine an "inert" material (e.g. Gold is a noble metal), the...

between the molten iron oxide and solid carbon at higher FeO concentrations. Weber (1993) has also demonstrated that the chromite ore cannot be reduced by CO gas alone, in the absence of carbon. The ore can be reduced by carbon, but the reaction may proceed through two steps: FeCrO 4 + 4C Æ Fe + 2Cr + 4 CO 2 and C + CO 2 Æ 2CO.

A significant level of sulfur release from the iron oxide will reduce the capacity of the reformer if sulfur absorbing equipment is not installed. Almost all commercially available oxide pellets have less than 0.01% sulfur and are suitable for direct reduction. Some types of lump ores contain 0.01% or less sulfur.

Oxide - Wikipedia

An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O 2– (molecular) ion. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth's crust consists of solid oxides, the result of elements being oxidized by the ...

Oxidation-Reduction Reactions

A classic demonstration of oxidation-reduction reactions involves placing a piece of copper wire into an aqueous solution of the Ag + ion. The reaction involves the net transfer of electrons from copper metal to Ag + ions to produce whiskers of silver metal that grow out from the copper wire and Cu 2+ ions.
