The minerals must go through chemical reactions to make pure metals. In order for the reactions to happen, chemicals must be added to ores that have been melted. High temperatures are needed to melt ores. Think about the ways you use aluminum foil in your home. It is put into hot ovens and over flames on a grill, but it does not melt.
