● As per the MMDR Amendment Act 2015 the state governments will conduct auction for grant of mineral concessions. The role of the central government is to prescribe the terms and conditions and procedures subject to which the auction shall be conducte(d) So first statement is wrong. [Economic Survey 2014-15 Vol2, page 140] ● Largest gold ore (primary) are located in Bihar (44%) followed by Rajasthan (25%) and Karnataka (21%), West Bengal, and Andhra Pradesh (3% each). So, Andhra Pradesh indeed has a gold mine, so #2 is wrong. ● Hematite and magnetite are the most important iron ores in India.....resources of hematite are spread in Andhra Pradesh, Assam, Bihar, Maharashtra, Madhya Pradesh, Meghalaya, Rajasthan and Uttar Pradesh. So, third statement is right.
