Haematite, Magnetite, Limonite & Siderite.
Haematite
Reddish; best quality; 70 per cent metallic content.
Found in Dharwad and Cuddapah rock systems of the peninsular India.
80 per cent of haematite reserves are in Odisha, Jharkhand, Chhattisgarh and Andhra Pradesh.
In the western section, Karnataka, Maharashtra and Goa has this kind of ore.
Magnetite
Black ore; 60 to 70 per cent metallic content.
Dharward and Cuddapah systems.
Magnetic quality.
Karnataka, Andhra Pradesh, Rajasthan, Tamil Nadu and Kerala.
Limonite
Inferior ores; yellowish in colour; 40 to 60 per cent iron metal.
Damuda series in Raniganj coal field, Garhwal in Uttarakhand, Mirzapur in Uttar Pradesh and Kangra valley of Himachal Pradesh.
Advantage == open cast mines == easy and cheap mining.
Siderite
‘Iron carbonate’; inferior quality; less than 40 per cent iron.
Contains many impurities {previous post}; mining is not economically variable.
However, it is self-fluxing due to presence of lime.
