Chemistry C1 3.6 Metallic issues.

HideShow resource information
What type of issues are associated with exploiting metal ores?
Social, economical and environmental issues.
1 of 10
What is the purpose of recycling?
It saves energy and limited resources.
2 of 10
What does mining for metal ores involve?
Digging up and processing large amounts of rock.
3 of 10
What is the environmental impact of mining for metal ores?
It can produce large amounts of waste material and effect large areas of the environment.
4 of 10
What is the advantage of recycling metals?
It saves the energy needed to extract the metals, and saves resources because less ore needs to be mined, also less fossil fuel is needed to provide the energy to extract the metal from its ore.
5 of 10
What are the benefits of using metals in construction?
They are strong, they can be bent into shape, they can be made into flexible wires and they are good electrical conductors.
6 of 10
What are the disadvantages of using metals in construction?
Obtaining metals from ores causes pollution and uses up limited resources, metals are more expensive than other materials such as concrete, and iron and steel can rust.
7 of 10
Why should we recycle aluminium cans?
To save: the energy needed to extract it from its ore, resources, fossil fuels, land needed for mining and/or landfill, other specified environmental impact.
8 of 10
What are the benefits and drawbacks of using steel for girders in buildings?
Benefits: strong, not brittle, can be shaped, can be cut or joined or welded, cheaper than alternative metals. Drawbacks: needs protection from corrosion, heavy/dense, needs energy to extract/produce, extraction causes pollution.
