FormsClassification of Iron Based on the varying percentages of carbon iron is broadly classified into the following 1 Pig iron Pig iron is the product of smelting iron ore It contains up to 5 carbon This carbon content is quite high and it makes the pig iron hard and brittle and thus difficult to work with Consequently pig iron is Earths most important iron ore deposits are found in sedimentary rocks They formed from chemical reactions that combined iron and oxygen in marine and fresh waters The two most important minerals in these deposits are iron oxides hematite Fe 2 O 3 and magnetite Fe 3 O 4 These iron ores have been mined to produce almost every iron and
