Question

Describe with an example how low reactive metals are extracted.​

Answer 1

Answer:

sThe less reactive metals are extracted by the reduction of their oxides by heat alone. Example: Mercury (II) sulphide ore is roasted in air when mercury (II) oxide is formed. When this mercury (II) oxide is heated to about 300oC, it decomposes to form mercury metal.

Answer 2

Metals more reactive than carbon, such as aluminium, are extracted by electrolysis, while metals less reactive than carbon, such as iron may be extracted by reduction with carbon.
