copper extraction and purifi ion - chemguide

The copper II ions in the chalcopyrite are reduced to copper I sulphide which is reduced further to copper metal in the final stage . The iron in the chalcopyrite ends up converted into an iron II sili e slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas. This is used to make sulphuric acid via

Extraction of iron from plant leaves by Fe II chelators

Ferric iron added to a plant extract was completely reduced in the darkness. These data seem to indi e that if extraction of ferric iron occurred it would be reduced and measured as ferrous iron. Thus the form of iron being extracted may be better called “active”; or “labile”; instead of ferrous iron. The use of o‐phe for the

Iron removal by physical chemical way - Lenntech

Thus the ferrous iron is oxidized in ferric iron which precipitates in iron hydroxide Fe OH 3. The precipitate is then separated from water by filtration on sand or decantation. The stage of precipitation by chemical oxidation can also be carried out with the stronger oxidants such as the chlorine dioxide ClO 2 ozone O 3 or the potassium permanganate KMnO 4 .

Thermodynamic Principles of Metallurgy: Ellingham Diagram

Extraction of iron from its oxide is done in a blast furnace. Here the ore mixes with coke and limestone in the furnace. Actually the reduction of the iron oxides happens at different temperatures. The lower part of the furnace is kept at a much higher temperature than the top. This process was developed after understanding the reactions with the help of thermodynamics. These reactions are as
