How Can You Find Iron
Iron mostly exists in the form of iron oxide, e.g. hematite (ferrous oxide). So what you found is mostly likely one of the 16 iron oxides known on earth. Of course the iron used to make our tools in everyday life doesn't come from backyard soil. Instead, iron is more economically extracted in large scale from iron ores using heavy equipment.
