More aluminium ore would have to be mined. Mining makes a mess of landscape. Ores need to be transported. Aluminium needs to be extracted which uses a lot of energy. It costs to send used aluminium to landfill.
Mar 10, 2015 · The metal reactivity series is a commonly taught concept in chemistry, placing the metals, as its name suggests, in order of reactivity from most reactive to least reactive. It''s also a useful tool in predicting the products of simple displacement reactions involving two different metals, as well
HSC Study Lab: Y11 Chemistry: Recycling aluminium YouTube. Lesson 3 Recycling Aluminium Recount the steps taken to recycle aluminium. Analyse information to compare the cost and energy expenditure involved in the extraction of aluminium from its ore and the recycling of aluminium.
As an AQA examiner for the new GCSE trilogy and triple science course I include a lot of ''past paper'' style questions in my lessons that match the type of questions students will be asked in examinations. petrol (topic 7), iron (topic 4/10), aluminium (topic 4) and copper (phytomining and bioleaching covered in topic 10) Review questions on
New scrap comes from factories which make articles from copper, brass or bronze. Their machines will produce offcuts and shavings that can be collected and returned for recycling. Copper is made with different purities depending on the appliion. The highest grade copper is electrical grade. It is 99.99% pure and is used for electrical cables
Methods of extraction Many metals are found in the Earth''s crust as ores. 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

Aluminium Cost and Recycling. Aluminium is the third most abundant element in the Earth''s crust after oxygen and silicon. It is the most abundant metal but it is more expensive to produce than iron because of the cost of the large amounts of electricity Home GCSE Chemistry GCSE Physics.
One advantage of using recycled copper is that if you compare with the increasing rate of mobile phone/telecommuniion and other metal based items sales, demand for copper materials also vastly
Use the students results to compare how effective the fuels are at producing heat energy. (3) Metals are produced from their ores but can also be obtained by recycling. GCSE Science 2011 GCSE GCSE Chemistry (5CH1H/01) Edexcel Limited. Registered in England and Wales No. 4496750
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.
Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply remelting the metal, which is far less expensive and energyintensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3), which must first be mined from bauxite ore and then refined using the Bayer process.

Revision summaries for Paper 1 AQA GCSE Chemistry 1 (this page) (separate (AQA GCSE sciencechemistry) 1.3.1 Be able to compare the properties of Group 1 metals with transition metals. Pure metals eg copper, gold, iron and aluminium, are too soft for many uses and so are mixed with other metals to make alloys which are harder.
Inorganic Chemistry: Includes essential ideas about redox reactions and electrolysis, and covers the trends in Period 3 and Groups 1, 2, 4 and 7 of the Periodic Table. Plus: lengthy sections on the chemistry of some important complex ions, and of common transition metals. Extraction and uses of aluminium, copper, iron, titanium and tungsten.
An aluminum alloy is a chemical composition where other elements are added to pure aluminum in order to enhance its properties, primarily to increase its strength. These other elements include iron, silicon, copper, magnesium, manganese and zinc at levels that combined may make up as much as 15 percent of the alloy by weight.
Oct 12, 2014 · In this video, we start by exploring two really important metals: titanium and aluminium. What makes them so expensive? Then we look at three good reasons why we need to recycle metals.
However metal–rich ores e.g. copper help revise O level importance of recycling metals chemistry how to succeed in questions on importance of recycling metals for gcse chemistry how to succeed at igcse chemistry how to succeed at O level chemistry a good website for free questions on importance of recycling metals to help to pass gcse
The aluminium is then made into large blocks called ingots. Each ingot contains about 1.6 million drinks cans. The ingots are sent to mills where they are rolled out, this gives the aluminium

Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.
the anode consists of an unrefined sample of the metal the hode is made of pure copper or a support metal such as stainless steel. 2 The electrolysis can be done using two weighed copper strips. This is to confirm that the mass gained at the hode is equal to the mass loss at the anode.
As part of their work on metals, GCSE chemistry students will look at some of the problems that arise in their extraction from ores. As with most things, there is a financial cost, but there''s also an environmental one. Revise what you learned in Year 10 and Year 11 by playing this interactive quiz.
