Essay on Iron Ore : Nature, Classification and Production

Essay # Classification of Iron Ore: According to usage, function-ability and composition, iron ores are principally of four major types: A. Magnetite (Fe 3 O 4): It is the richest among all iron ores with little impurities. The iron content varies between 70 to 72.5%. It contains magnetic properties, therefore it is suitable for electrical

Iron ore: Mineral information, data and localities.

Ferruginous rock containing one or more minerals from which metallic iron may be profitably extracted. The chief ores of iron consist mainly of the oxides: hematite, Fe2O3 ; goethite, alpha -FeO(OH); magnetite, Fe3O4; and the carbonate, siderite FeCO3.

Mineral Classification of minerals Britannica

Mineral Mineral Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level

Characterization of Chemical Composition and

However, for classification and evaluation of quality, the raw iron ores can be divided into three basic classes depending on the total Fe content: (i) high-grade iron ores with a total Fe content above 65%, (ii) medium- or average-grade ores with varied Fe contents in the range between 62–64%, and (iii) low-grade ores with Fe contents below

Developments in iron ore comminution and classification

Jan 01, 2015· Iron ore grinding and classification. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits are much finer-grained and therefore require significant grinding to liberate the magnetite from its silicate matrix. Various magnetite ore grinding flowsheets have been implemented in the past, including

Extraction of Iron Metallurgy Blast Furnace and Reactions

A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.
