Ores
A metal ore is a rock which contains enough metal to make it worthwhile extracting the metal from it.
1 of 14
Getting metals from rocks
Metals are extracted from their ores chemically using reduction or by electrolysis.
2 of 14
Reduction
removal of oxygen
3 of 14
Metal extracted by reduction with carbon
a metal can be extracted from its ore chemically by reduction using carbon.
4 of 14
Reactivity series
metals higher than carbon extracted by electrolysis and metals below carbon extracted by reduction
5 of 14
Smelting
the ore is heated in a furnace
6 of 14
Eectrolysis
splitting up with electricity-breaking down of a substance usinf electricity
7 of 14
Bioleaching
bacteria used to separate copper from copper sulphate.
8 of 14
Phytomining
growing plains in soil that contains copper, plants harvested,dried and burned in a furnace.
9 of 14
Crude oil
A mixture of hydrocarbons
10 of 14
Fractional distillation
Heated crude oil at the bottom. The vaporized oil rises up the column-the various fractions tap of different levels where they condense
11 of 14
Cracking
Splitting up long-chain hydrocarbons
12 of 14
Thermal decomposition
breaking molecules down by heating them
13 of 14
Alkenes
have a c=c double bond-unsaturated because they can make more bonds. Double bonds can open up.
