AND HOW DO WE GET IRON?

• Iron comes from iron ores
• Iron is commonly found in many countries
• China has the highest iron count
• 90 million metric tonnes of iron have come from China

• Iron is gathered by the process of filtration.
• No harm is done, because iron is nontoxic
• Iron is used to make steel and produce hemoglobin
