They have to be extracted from their ores through processes such as electrolysis, using a blast furnace or by reacting with more reactive material. In many cases the ore is an oxide of the metal, therefore the extraction of these metals is a reduction process since oxygen is being removed. Common examples of oxide ores are iron and aluminium ...Web
