excration of iron
Iron is an essential mineral used in many functions, specifically in the transport of oxygen. Iron deficiency can occur through poor diet, or as a consequence of blood loss through menstruation or injury.
Extraction of Iron. Share My Lesson is a destination for educators who dedicate their time and professional expertise to provide the best education for students everywhere.
Extraction of Iron. Iron is about 21 % of total metal of earth's crust and 6.2 % of total elements. It belongs to transition group of the periodic table.
It comes with many limitations including high waste emissions etc. Corex is evidently more efficient than the blast furnace, although there are few drawbacks, the benefits outweigh these; resulting in a better, and more efficient extraction process.
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast ...

Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust.
Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less. Coke is a substance made by heating coal until it becomes almost pure carbon.
5.4 describe and explain the main reactions involved in the extraction of iron from iron ore (Haematite), using coke, limestone and air in a blast furnace.
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace.

Extracting iron Here I use a gentle supply of oxygen at the surface of the reaction mixture to generate the high temperatures (>1000ºC) necessary for the direct reduction of iron oxide with carbon. 1 The resulting sparks, smell and bright light make for a dramatic demon-stration, and the resulting lump of iron can be handled when cooled.
Extracting iron from iron ore . In the 12th century, men started to mine iron ore from rock. They learnt how to recognize rock that contained iron ore and broke off …
Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. iron; production of steelIron ore is one of the most abundant elements on Earth, and ...
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

Jul 21, 2014· Iron ores are reduced by coke (carbon) in a blast furnace. The process is summarised in the diagram below. Hottest part of the furnace At the bottom of the furnace, adjacent to the hot air blast entry points, the temperature reaches around 1800ºC, and represents the hottest part of the furnace. Ascending vertically, the furnace temperature…
The first really useful metallic alloy to be discovered was bronze in the Bronze Age. Bronze is not an element (like gold and silver) but an alloy (metal mixture) of copper and tin. Bronze was used extensively for tools and weapons. After the Bronze Age came the Iron Age. People discovered that a ...
This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. 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 ...
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.
