There are four main varieties of iron ore. They are as follows:

• Hematite- It has a high iron content of around 70%.
• Magnetite- It is the most important industrial ore with a lower iron content.
• Limonite- Which is found in sedimentary rocks with an iron content less than 50%.
• Siderite- Has a low iron content about 20%-30%.
