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.

The reactivity series shows metals in order of reactivity. The reactivity of a metal is related to its tendency to form positive ions. Iron and aluminium are extracted from their ores in various ways.
Extraction and uses of aluminium. Note: You may find all sorts of other formulae given for the product from this reaction.These range from NaAlO 2 (which is a dehydrated form of the one in the equation) to Na 3 Al(OH) 6 (which is a different product altogether).. What you actually get will depend on things like the temperature and the concentration of the sodium hydroxide solution.
Extraction of iron Very unreactive metals are found directly in the ground as elements, eg. gold. Most metals are found in ores where they have reacted with other elements. Ores are rocks containing enough metal to make it economical to extract. We can extract the iron by reacting the iron oxide with a more reactive element.
Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table.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.. In its metallic state, iron is rare in the ...
Extraction of Metals. History ().. After the Bronze Age came the Iron Age. People discovered that a high temperature coal fire could be used for the extraction of iron from iron ore. The extraction of iron today is done in a blast furnace.. The Iron Age began in Asia and Africa in 1,100 B.C. and came to Britain in 500 B.C. In many ways, we are still in the Iron Age - take a look around.
Introduction Methods of Extraction Preliminary Steps Before Extraction Methods of Ore Concentration The Metals Sodium Aluminium Zinc Iron Copper ... METALS: EXTRACTION PROPERTIES AND USES - Form 4 Chemistry notes
Aluminum is extracted from aluminum oxide by a process called electrolysis. First of all, aluminum oxide needs to be in molten form to extract the aluminum ions. Aluminum oxide, however, has a high melting point. Therefore, aluminum oxide is dissolved in molten cryolite.
Mar 11, 2015· Raw Materials • Ore bauxite aluminium oxide • The ore is dissolved in cryolite to lower the melting point. 4. Aluminium: ores • It occurs as bauxite ore which is a form of aluminium oxide. • Because aluminium is so reactive carbon is unable to pull away the oxygen from it. • It is extracted by electrolysis of moltenmolten bauxite.
Feb 05, 2014· Extraction of iron from its oxides:In a Blast furnace Oxide ores of iron, after concentration through calcination/roasting are mixed with limestone and …
Electrolysis: Used in extracting aluminium and extracting sodium from rock salt. In the case of the rock salt, it is first melted in giant steel tanks: The extraction of aluminium is dealt with in a separate learn its within this topic. Heating with Carbon monoxide: Used for extracting iron from iron …
Carbon reduction is a method for extracting metals with an intermediate reactivity from ore. Iron ore blast furnace. (Image: zephylwer0, Pixabay) Electrolysis. Metals that are more reactive, such as aluminium and magnesium, cannot be extracted from minerals by carbon reduction.
How are metals extracted from mineral ores? How do we make iron, steel, other alloys, aluminium, sodium, copper, zinc, titanium and chromium. The six linked pages include an introduction to metal extraction or metal manufacture and production. There are detailed notes on the extraction of iron and its conversion to steel. The extraction and manufacture of aluminium and sodium are described.
Iron: Pure iron does not have a variety of uses. But alloys of iron such as steel are highly useful. Alloys are nothing but a mixture of different types of metals. Alloys of Irons are used to make cars, nails, bridges etc. We are going to discuss in details about the different types of iron in the extraction of the iron part.

An ore is any naturally-occurring source of a metal that you caneconomically extract the metal from. Aluminium, for example, is the most commonmetal in the Earth's crust, occurring in all sorts of minerals.
Aluminum is extracted from bauxite ore by way of the Bayer process. This requires a great deal of electricity; consequently, a large amount of aluminum is processed in Iceland, which gets its electricity through geothermal energy. To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash.
P rinciples of Metal Extraction: Metals are found in the combined state in ores where they exist as positive ions. During the extraction of metals, the metallic ions must first be reduced to the corresponding metal atoms. This reduction process can be done electrolytically or …
