Summary:Types of Iron Ore: Haematite, Magnetite, Limonite,Siderite. The most advanced iron ore mining and crushing equipment for different types of iron ore.
Types of Iron Ore
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.
Mineral Processing And Ore Metallurgy Technology
In order to improve the self-sufficiency rate of iron ore and get rid of the shackles of foreign mining giants, a great deal of research work has been carried out by relevant researchers around the efficient utilization of iron ore resources.
China is the world’s largest importer of iron ore, which imports accounted for one-third of the world’s total in recent decades, Has the most advanced iron ore mining and crushing equipment.
