The reactivity series and metal extraction The reactivity of a metal determines how it is extracted. Metals above carbon in the reactivity series must be extracted using electrolysis. Metals less reactive than carbon can be extracted from their ores by reduction. Copper, silver, gold and platinum can occur in their pure form (natively) and do not
Reduction of Metals (Extraction from Ore) - A-Level Chemistry
4.8.2.1 Metal extraction by reduction of oxides. Explain, using the position of carbon in the reactivity series, the principles of industrial processes used to extract metals, including extraction of a non-ferrous metal. AQA Combined science: Trilogy. 5.4 Chemical changes. 5.4.1 Reactivity of metals. 5.4.1.3 Extraction of metals and reduction
We can use carbon to reduce the oxides of metals below aluminium in the Reactivity Series. Because of this, carbon is used in the extraction of zinc, iron, and lead. This is a relatively cheap way to extract metals because carbon is readily available from coal. The extraction of metals from ores can cause environmental problems.

Metals - extraction with carbon. docx, 4 . Metals and their uses info sheets. docx, 158 KB. LOs and Extracting Copper instructions. About this resource. Info. Created: Feb 6, 2014 ...
There are five different types of iron Cast iron, Mild Steel, Wrought Iron, High-carbon steel, Stainless steel. It is based on their amount of carbon content they have. Carbon is used to extract iron, so some carbon remains with the iron metal.
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.
The carbon displaces the metal from the compound, and removes the oxygen from the oxide. This leaves the metal. The table summarises the extraction methods used for different metals.
Nov 20, 2015· A short explanation of how to extract metal from its oxide ore. ... Edexcel PCA GCSE Science Extraction of metal using carbon David Stalford. Loading... Unsubscribe from David Stalford?
The dust of this metal is used in paints. It is used in the extraction of manganese and chromium from its oxides. As it is a soft metal and it can be moulded into any shape it is used in the manufacturing of storage cans. Aluminium after iron is the most commonly used metal.
Reduction with carbon is often used to extract these metals and requires less energy to reduce them to extract the metal. Therefore, the method of extraction of a metal from its ore depends on the ...
In this classic experiment, from the Royal Society of Chemistry, students extract metals from their metal oxides using carbon. By strongly heating a mixture of copper oxide and charcoal students will observe small amounts of copper metals produced in the mixture when cooled. The resource is set out as teachers' notes followed by the students' page which presents the task to be investigated.
Carbon is in the List of convenient reducing agents, so it reduces metals easily. It can also reduce Zinc Oxide which cannot be reduced by other convenient reducing agents like CO, H2 or NH3. However, when it has to reduce a metallic oxide, Carbon dioxide gas is evolved which leads to global warming.

Carbon may also be left in the metal as an impurity. Sometimes this can be removed afterwards (for example, in the extraction of iron); sometimes it can't (for example in producing titanium), and a different method would have to be used in cases like this. Reduction using a more reactive metal
Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace.. Hot air is blasted into the furnace causing coke (carbon) to burn rapidly producing carbon dioxide and raising the temperature to 2000 °C.. carbon + oxygen carbon dioxide + heat. C (s) + O 2(g) CO 2(g) . The carbon dioxide then ...
Jun 30, 2005· Fig. 3 shows the variation in the percentage removal of heavy metals with contact time using 10 g/l of carbon aerogel at pH 6 for varying initial metal ions concentration ranging from 1 to 5 mg/l. It is observed that for Hg(II) ions, the percentage removal is .
Metals are extracted from their ores. An ore is a mineral, which is a metal compound that contains enough quantity of the metal to be extracted. The picture shows extraction of iron ore in a mine. Carbon is used to extract metals from their ores. This method involves reduction. Reduction means gain of electrons and loss of oxygen (see diagram).
The metal in the oxide is then reduced by carbon monoxide and the product of the reaction will be metal and carbon dioxide. metal oxide + carbon monoxide → metal + carbon dioxide ** The chemistry of metal extraction is very complicated, so when we simplify the reactions it is not really possible to be accurate about what the exact nature of ...
Jan 11, 2017· Lesson slides for the teaching of ores and extracting metals by displacement with carbon. Videos also included which show displacement of carbon from carbon dioxide by magnesium. Practical instructions included for extraction of copper from copper (II) oxide. Scaffolded worksheet assists students in capturing key notes.
Oct 15, 2018· There are five different types of iron Cast iron, Mild Steel, Wrought Iron, High-carbon steel, Stainless steel. It is based on their amount of carbon content they have. Carbon is used to extract iron, so some carbon remains with the iron metal.
Mar 17, 2019· This video explains the terms 'oxidation' and 'reduction', and then runs through an example how we can use carbon to reduce certain metal oxides - forming pure metals in the process.
Obtaining metals from metal oxides. Carbon is a non-metal but it is more reactive than some metals. This means that some metals can be extracted. from their metal oxides using carbon.
The siderophiles The extraction of Au and the Pt group metals and their purification. 3 Pyrometallurgy of copper.
