1. L.O: To know how different metals are collected

2.  Where do metals come from?  What is an ore?  In the back of your book, name as many metals as you can 04/06/2016

3. 1. Set up your bunsen, tripod, heatproof mat and clay triangle 2. Place 2 spatulas of your metal oxide (lead oxide, copper oxide or iron oxide) into a crucible 3. Add a spatula of carbon to the crucible 4. Stir the mixture well 5. Put the lid on the crucible and place it over the bunsen on the clay triangle 6. Leave for 30mins. What do you expect to see?

5. 04/06/2016 Oxide Iron Potassium Sodium Calcium Magnesium Aluminium Carbon Zinc Iron Tin Lead Copper Silver Gold Platinum Metals ABOVE CARBON, because of their high reactivity, are extracted by ELECTROLYSIS Metals BELOW CARBON are extracted by heating them with carbon in a BLAST FURNACE. This is a “reduction reaction” These LOW REACTIVITY metals won’t need to be extracted because they are SO unreactive you’ll find them on their own, not in a metal oxide Carbon

6. 04/06/2016 A METAL ORE is a mineral or mixture of minerals from which it is “economically viable” to extract some metal. To “extract” a metal from a metal oxide we need to REDUCE the oxygen. This is called a REDUCTION reaction. To put it simply: Most ores contain METAL OXIDES (e.g. rust = iron oxide). Some definitions: Iron Oxide Iron ore “Reduce” the oxygen to make iron

7. e.g. Zinc oxide + Carbon  Zinc + Carbon dioxide

8. 04/06/2016 Iron produced by the blast furnace (“cast iron”) contains about 96% iron and 4% impurities. These impurities make it very brittle and easy to break. Ironbridge, Shropshire – made out of cast iron and safe for horses and carts but not modern vehicles.
