The correct answer is 1 and 2 only. Key Points. There are four types of iron ores, viz. hematite, magnetite, limonite, and siderite. India is endowed with fairly abundant resources of iron ore and has the largest reserve of iron ore in Asia. The two main types of ore found in India are hematite and magnetite. Hence Option 1 is correct.
