gcse 1 Introduction to the Extraction of Metals method
In extracting metals from ores you have to reverse the process eg by heating the ore with carbon (coke or charcoal) in a very hot smelting furnace eg in a blast furnace to make iron iron oxide ore + carbon ===> free iron + carbon dioxide waste gas Fe 3 O 4 + 2C ===> 3Fe + 2CO 2 The iron oxide is reduced (oxygen loss) and the carbon
