An evolving view on biogeochemical cycling of iron Nature
Biogeochemical cycling of iron is crucial to many environmental processes, such as ocean productivity, carbon storage, greenhouse gas emissions and the fate of Inhibitor extraction process. Plant extracts are one such option that may be utilized as an eco-friendly substitute. It has been shown via literature reviews that many different plants extracts are employed as corrosion inhibitors. Bark, leaves, fruits, peels, seeds, roots, flowers, and even complete plant extracts fall under this category.Advances of plant-extracted inhibitors in metal corrosion

How to Extract Iron from Hematite: Methods and Plants
It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.The maximum iron extraction efficiency was 52%.

Extraction of Iron Metallurgy Blast Furnace and Reactions
It’s a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.Sesa Goa Iron Ore, a Vedanta Group company, is engaged in the exploration, mining, and processing of iron ore. The company was founded in 1954, as Scambi Economic SA Goa. Since then, it has grown to be one of the country's top low-cost producers of iron ore.

Extraction of Iron from Copper-Plant Slag Springer
Abstract—In the production of copper from sulfide ore, slag accumulates at the processing plant. In the pres-ent work, the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200°C are investigated. Experiments show that most of the iron present in such slag4.3 Plasma processing of manganiferous iron ore. Manganiferous iron ore is the type of lean manganese ore containing a maximum about 10–15% of Mn.
