Redox Reactions

For centuries, humans have been extracting metals from molten ores. Today, the basic technique remains the same, but how does extraction work?

Chemistry - Reactions - Learning Points.

Metals can be extracted from rocks if they are heated with charcoal.

A redox reaction is a process that involves reduction and oxidation.

Reduction is the removal of oxygen, and this requires a form of carbon and a heat source.

Iron is extracted within a blast furnace, in which highly exothermic reactions take place.
