Extraction of Iron | Metallurgy | Blast Furnace and Reactions

The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore

Ellingham diagram Wikipedia

Ellingham diagrams are a particular graphical form of the principle that the thermodynamic feasibility of a reaction depends on the sign of ΔG, the Gibbs free energy change, which is equal to ΔH − TΔS, where ΔH is the enthalpy change and ΔS is the entropy change The Ellingham diagram plots the Gibbs free energy change (ΔG) for each oxidation reaction as a function of temperature

Soxhlet Extraction an overview | ScienceDirect Topics

Soxhlet extraction is an exhaustive extraction technique widely applied to analytes that are sufficiently thermally stable The extraction solvent is continuously cycled though the matrix, by boiling and condensation, with the sample being collected in the hot solvent The technique is not selective (apart from the choice of extraction solvent) and generally further cleanup and concentration are required

Ellingham diagram Wikipedia

An Ellingham diagram is a graph showing the temperature dependence of the stability of compounds This analysis is usually used to evaluate the ease of reduction of metal oxides and sulfides These diagrams were first constructed by Harold Ellingham in 1944 In metallurgy, the Ellingham diagram is used to predict the equilibrium temperature between a metal, its oxide, and oxygen — and by extension, reactions of a metal with sulfur, nitrogen, and other nonmetals The diagrams

Thermodynamic Principles of Metallurgy: Ellingham

Ellingham Diagram An Ellingham diagram shows the relation between temperature and the stability of a compound It is basically a graphical representation of Gibbs Energy Flow In metallurgy, we make use of the Ellingham diagram to plot the reduction process equations This helps us to find the most suitable reducing agent when we reduce oxides to give us pure metals Let us take a look at some important properties of the Ellingham Diagram
