Extracting metals

Question 1

What does extracting a metal from its ore depend on?

Answer 1

Its position the reactivity series.

Question 2

Two ways to extract metals

Answer 2

Electrolysis (all metals)
Heating with carbon (less reactive metals)

Question 3

Electrolysis

Answer 3

Any metal can be extracted using electrolysis and produces a very pure metal. However, it is very expensive as it uses lots of electricity. Therefore only metals more reactive than carbon are extracted using electrolysis.

Question 4

Heating with carbon

Answer 4

This method is used for metals that are less
reactive than carbon. The metal is extracted from its ore by heating with carbon. This method is much cheaper as it uses less energy. metal oxide + carbon → metal + carbon dioxide
