The slag is lighter than 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
Extraction process of iron from its ore - extraction process of iron from its ore extraction process of iron from its ore iron extraction 4college.co.uk salters chemistry. from the table above, it is evident that the iron ores contain oxygen. . these are in short supply and so the iron first goes through agglomerating processes fuse.
The method that is used in the extraction of metal from its ore depends on the position of the metal in the reactivity series of metals. metals that are located lower than carbon in the reactivity series of metals can be extracted using the reduction of metal oxide by carbon in a blast furnace.
An ore is usually a compound of the metal mixed with impurities. when the metal is dug up, a method must be used to separate the metal from the rest of the ore. this is called extracting the metal. the method of extraction depends on how reactive the metal is. the more reactive the metal, the more difficult it is to extract from its compound.
This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal like sodium or magnesium, and by electrolysis. details for the extraction of aluminium, copper, iron and titanium are given in separate pages in this section.
The commonest ore used in the extraction of copper is chalcopyrite cufes 2 also known as copper pyrites and other such sulfides. the percentage of copper in the actual ore is too low for direct extraction of copper to be viable. the concentration of ore is required and it is done by the froth flotation method. concentration of ore
