This method of extraction works because carbon is more reactive than iron, so it can displace iron from iron compounds Extracting a metal by heating with carbon is cheaper than using electrolysis

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

Stainless steel is an iron containing alloya substance made up of two or more chemical elementsused in a wide range of applications It has excellent resistance to stain or rust due to its chromium content, usually from 12 to 20 percent of the alloy There are more than 57 stainless steels

Wrought Iron Process Wrought iron is produced by pummeling the pig iron using mechanically driven hammers in a wrought iron works This process prepares it for the next stage which is the heating and forging to the desired wrought iron designs and shapes This used to be an art of the blacksmith, but is now normally carried out by machines

Nov 08, 2012 The extraction of iron metal from iron ore A hot drink cooling to room temperature Which of the following processes are spontaneous? The combustion of natural gas The extraction of iron metal from iron ore A hot drink cooling to room temperature Drawing heat energy from the ocean's surface to power a ship

The slag is lighter then molten iron and to floats on the surface of the iron The formation of prevents the oxidation of iron d Zone of Reduction: This is the most important zone and has temperature of 600 700 0 c In this zone Fe 2 O 3 is reduced to iron by co in three steps 3Fe 2 O 3 + CO 2Fe 3 O 4 + CO 2

May 22, 2009 Extraction of Iron Step1: Concentration The ore is crushed in crushers and is broken to small pieces It is concentrated with gravity separation process in which it is washed with water to remove clay, sand, etc 8 Steps of Extraction Step1: Concentration Step2: Calcination The ore is then heated in absence of air calcined
