description of the extraction of iron ore

It is in the blast furnace that extraction of iron occurs 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

Extracting iron from iron ore using a Blast Furnace The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke Coke is produced by heating coal in the absence of air Coke is cheap and provides both the reducing agent for the reaction and also the heat source

Alumina Extraction Problem In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch

extracting iron from iron ore using blast furnace: Extracting iron from its ore requires a series of steps to be followed and is considered as the penultimate process in metallurgy The steps need the ore to be concentrated first, followed by the extraction of the metal from the concentrated ore

Iron Extraction Process In the blast furnace process, the first step on the way towards heavy plate, pig iron is produced from iron ore The composition of the ore and additions is accurately adjusted to the final products of AG der Dillinger Hüttenwerke and Saarstahl AG

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron Fe It almost always consists of iron oxides, the primary forms of which are magnetite Fe 3 O 4 and hematite Fe 2 O 3 Iron ore is the source of primary iron for the world's iron and steel industries

Determination of Iron Ore by Redox Titration Determination of Iron in Ore by Redox Titration Oxidationreduction reactions are suitable for titration reactions if they are rapid and quantitative The end point can be seen by indicators or by instrumental methods such as potentiometry Potentiometric Titration of Ferrous Ion

Mar 14, 2014 The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state It consists of several distinct steps The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and
