A key step in the extraction of iron from its ore is FeO(s) + CO(g) ⇌ Fe(s) + CO2(g) Kp = 0.403 at 1,000°C This step occurs in the 700°C to 1,200°C zone within a blast furnace. What are the equilibrium partial pressures of CO(g) and CO2(g) when 1.0900 atm of CO(g) and excess FeO(s) react in a sealed container at 1000°C?
Ni increases the overall cost of nickel extraction. The authors have proposed a virtually SO 2-free and one-step nickel extraction method, by which Ni values in the sulfide concentrate can be extracted into a ferronickel (FeNi) alloy with sulfur remaining in the solid as iron sulfide. There-fore, the evolution of SO

The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: [2CuFeS_2 + 2SiO_2 +4O_2 rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 label{1} ]
Extraction of iron or its metallurgy is the process of obtaining this metal in a form where it can be put to practical use, and this process of extraction consists of three stages: Ore dressing, Reduction of ores and Iron production. ... After the reduction of iron ores in the blast furnace or Midrex furnace, the third step in which the ...

The first step is commonly crushing, in which large pieces of ore are reduced to a smaller size. ... Extraction of iron takes place on an industrial scale in blast furnaces. Blast furnaces are a common part of large industrial steelmaking plants, which also include coke ovens, sintering beds, and other areas for ore dressing. Iron is extracted ...
The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as iron silicate slag. Most of the sulphur in Chalcopyrite turns into Sulphur dioxide (SO 2).
A process route to separate bismuth, iron, and rare earth elements from a solution containing nickel and magnesium through one-step extraction and two-step stripping was introduced. • The coextraction of Bi(III), Fe(III), and RE(III) was achieved by controlling the pH, avoiding the production of bismuth hydrolysis and rare earth double …
