COAL PPT |authorSTREAM

The Answer = Smelting When carbon is added to Iron Ore at high temperatures and in the presence of added oxygen from an external source (i.e. a blower or fan), it reacts with the added oxygen to form CO2 (Carbon Dioxide) and CO (Carbon Monoxide). These molecules then react with the oxygen in the iron ore and leave pure iron.
