Extracting Metals
- Limestone
- Quarries
- Noisy
- Creates Jobs
- Pollution
- Better Healthcare
- Damages Landscape
- Improves Transport Links
- Lots of Traffic created
- Noisy
- Cement
- Result of Heating Limestone and
Clay
- Limestone= Calcium Carbonate
- Calcium Carbonate =
- Calcium Carbonate =
- Limestone= Calcium Carbonate
- DOES NOT DRY OUT
- Mortar
- Mixing Cement, Sand and
Water
- DOES NOT DRY
OUT
- Binds bricks together
- Mixing Cement, Sand and
Water
- Concrete
- Very Strong
- DOES NOT DRY OUT
- Mixing Cement, Sand, Gravel and
Water
- Used in foundations for buildings/bridges
- Very Strong
- Result of Heating Limestone and
Clay
- Ores
- Only used when the ore contains enough
metal to make extraction worthwhile
- Metal Oxides
- Can be SMELTED directly
- Smelting
- The Ore is crushed and concentrated to
remove rock containing little/no metal
- The Ore is crushed and concentrated to
remove rock containing little/no metal
- Smelting
- Changed into metals by REDUCTION
- Reduction
- Removing the Oxygen from the compound
- Heating in a furnace with carbon IF the metal
is below carbon in the reactivity series
- Limestone is added to remove
impurities from the ore which forms
slag
- Metals ABOVE Carbon in the
reactivity series are extracted
using ELECTROLYSIS
- Electrolysis produces Oxygen Gas
- Electrolysis produces Oxygen Gas
- Limestone is added to remove
impurities from the ore which forms
slag
- Removing the Oxygen from the compound
- Reduction
- Can be SMELTED directly
- Only used when the ore contains enough
metal to make extraction worthwhile
- Quarries
- Iron
- Blast Furnaces
- Iron Ore, Coke and Limestone are fed
into the top of the blast furnace
- Molten Iron and Slag collect at the bottom
- Carbon Monoxide is produced from burning Oxygen and Coke
- Coke = pure Carbon
- Carbon Monoxide reduces iron oxide to iron, and
is oxidised to carbon dioxide
- Coke = pure Carbon
- Produces iron
- produces carbon dioxide
- Carbon Monoxide reduces iron oxide to iron,
and is oxidised to carbon dioxide
- Carbon Monoxide reduces iron oxide to iron,
and is oxidised to carbon dioxide
- Iron Ore, Coke and Limestone are fed
into the top of the blast furnace
- Limestone reacts with
impurities and creates slag
which floats on top of the iron
- Blast Furnaces
- Oxidation
- oxygen is added to a substance
- oxygen is added to a substance
- Reduction
- oxygen is removed from a substance
- oxygen is removed from a substance
