What are the properties of a metal?
-Sonorous , ductile, solids, magnetic, good conductors of heat and electricity and malleable.
1 of 38
Where are metals found?
Earth's Crust
2 of 38
What is a metal ore?
A rock that contains a lot of a type of metal in it
3 of 38
What is displacement?
A more reactive metal would displace the less reactive
4 of 38
What is carbon more reactive than?
Copper, lead, iron and zinc
5 of 38
What is the process of smelting?
1) Roasting 2)Reduction 3) Fluxes
6 of 38
What are the uses of iron?
Watch, cutlery, Earth's core
7 of 38
What is the iron's ore?
8 of 38
What raw materials are needed to extract iron?
Carbon- coke, limestone and air.
9 of 38
What happens when they combine together?
Carbon and oxygen is produced- carbon monoxide
10 of 38
What can form when iron oxide and carbon monoxide react?
Carbon dioxide and molten iron
11 of 38
How is **** made?
When hot air is added to the furnace
12 of 38
What is an alloy?
Two metals or more that combine together
13 of 38
Why are alloys made?
To make metals harder
14 of 38
What are smart alloys?
An alloy that remembers their shape
15 of 38
How are alloys different to metals?
They are irregular, more spaced and the layers cannot slide over eachother
16 of 38
How is iron extracted?
Through a blast furnace ( cast iron)
17 of 38
What does it contain?
96% impure iron and 4% carbon and other impurities
18 of 38
What is the ore of copper?
19 of 38
What is electrolysis?
Running an electric current through an electrolyte.
20 of 38
Electrolyte is...
Solution containing ions that conduct electricity
21 of 38
Where does the impure copper go?
To the anode
22 of 38
Where does the pure copper go?
To cathode
23 of 38
What happens to the anode?
It starts to dissolve
24 of 38
What happens to the cathode?
It is coated with copper, gets bigger
25 of 38
What are aluminium's properties?
low density, strong,good electrical and heat conductor
26 of 38
What is aluminium used for?
Overhead power lines, aircraft bodies
27 of 38
What are titanium's properties?
heavy weight, resistant to corrosion, high mp
28 of 38
What is titanium used for?
Rockets and hip replacements
29 of 38
Remember that Panic means
Positive Anode Negative Is Cathode
30 of 38
What is aluminium's ore?
31 of 38
What about titanium's ore?
32 of 38
How would you extract titanium?
first convert it to tetrachloride, react with magnesium
33 of 38
What is open-cast mining?
It is when you move mountains which leaves holes and creates mountains of waste rock elsewhere.
34 of 38
What are finite resources?
When something runs out but cannot be replaced
35 of 38
What is bioleaching?
Uses less electricity and produces no waste gases. It's when bacteria grow on ores and the solution is extracted through electrolysis or displacement
36 of 38
What is phytomining?
Burning plants that leave ash and contain copper. It's extracted by electrolysis.
37 of 38
What is a catalytic converter?
Carbon monoxide -> Carbon Dioxide
