iron (III) oxide + carbon ==> iron + carbon dioxide. 2Fe2O3 + 3C ==> 4Fe + 3CO2. 2Fe2O3(s) + 3C (g) ==> 4Fe (l/s) + 3CO2(g) (equation with state symbols) I'm afraid there are quite a few possible equations and most do occur to some extent somewhere in the blast furnace.

Extraction of Iron Concentration of Ore - An Overview

23-09-2019  The extraction of iron begins with concentration through calcination which is a process in a limited supply of oxygen applied to ores to bring thermal decomposition. An ore of a metal is an impure source. It consists of many impurities other than metal such as sand, clay, etc.

Extraction of Iron (III) from Aqueous Sulfate Solutions by ...

The extraction of iron (III) from aqueous sulfate so­lutions by didecylamine has been investigated by Baes who first interpreted his results by assuming ex­traction of partially hydrolyzed species Fe(OH)S04. Another mechanism was suggested by Good et al. who explained their observations by assuming that in the extraction by Primene 81R the following ion-

Iron extraction and steelmaking - Chem Not Cheem

18-08-2020  3. Blasting our climate: carbon dioxide is the main by-product of iron extraction. The star of the show in the blast furnace is coke.First, it acts a fuel to provide energy for the reduction of haematite. Second, coke forms carbon monoxide, which then serves as the reducing agent to reduce haematite to iron.. Unfortunately, as haematite is reduced to iron, coke is concomitantly oxidised to ...

Iron removal by physical chemical way - Lenntech

In aerated water, the redox potential of the water is such as it allows an oxidation of the ferrous iron in ferric iron which precipitates then in iron hydroxide, Fe(OH) 3, thus allowing a natural removal of dissolved iron. 4 Fe2+ 3 O2 --> 2 Fe2O3. Fe2O3 + 3 H2O --> 2Fe(OH)3
