Slide 18 of 45
Extracting
Metals from their Ores
The metals that are less
reactive than carbon in the reactivity series such as lead, tin and iron can have their oxides heated in the presence of carbon.
The oxides then undergo reduction and you are left with
the metal.
The extraction of iron and zinc from its ore using carbon is a very
important industrial process that you will
need to study carefully, you will
also need to know the important implications it has on the environment.
