Different Types of Iron Ore

Iron Ore can look like many things depending on what grade the ore is if it is a high grade such as Hematite (700%) or Magnetite (724%) then the ore will have a silver gray type but if the ore has a lower iron content like Goethite (629%) or Siderite (483%) then it is more likely to look like the type of rock that it was mined from Units.
