increase of iron ore by crushing in tamil nadu

five potential tamil nadu sites for mining platinum, iron ore

The state department of mining can explore the commercial value of these sites, once the central notification now under process is finished, S. Raju, Deputy Director General of Geology told Deccan Chronicle.

After six years of platinum and other investigations in Tamil Nadu, 25 sites threw surprises for our geologists and of this, 10 spots were explored in detail and the same was shared to the centre recently.

Of the 10 explored areas, five spots including Thuraipadi in Thiruvannamalai, Thirumangaradhu in Tiruppur, Sambalpatti in Rasipuram, Sanganagiri in Tiruchengode and Namakkal have been found to be viable sites for commercial mining.

There are also small private areas during our exploration showing signs of minerals, but such sites will not be commercially viable due to their small geographic size. Now it is for the state to float global tenders to identify the right firms with expertise to tap the minerals, he added.

According to GSI sources, Tamil Nadu has rich sources of minerals and there are rocks found with rich magnesium oxide content of above 30 per cent and 30 colours of granites are found in Madurai region of TN.

a study on removal of clay minerals from barbil region iron ore; effect of scrubbing followed by pelletization | springerlink

The presence of appreciable quantity of clay mineral in Indian hematite ore needs an attrition technique using screw scrubber in the beneficiation circuit to remove the ultrafine clays and avoid downstream operational problems. Spectroscopic analysis revealed that iron ore samples obtained from the Barbil region of Odisha contain a high amount of silica and alumina in the form of clay minerals (e.g., kaolinite) contributed as a loss on ignition (LOI) in the iron-making process. Iron ore fines of below 10 mm size were subjected to a laboratory-scale screw scrubber, and the effectiveness of scrubbing as well as the pelletization of the scrubbed product was investigated. The screw scrubber in the beneficiation circuit helps to remove the clay minerals, causes an increase in iron values from 63.65% Fe(T) to 66.18% Fe(T), with improved physical (CCS of 325 kg/pellet) and metallurgical (RDI of 2.24%) pellet properties.

jindal steeljoins pre-emptionbandwagon for iron ore supply in odisha- the new indian express

Acknowledging the fact that steel industries in the State are reeling under severe iron ore crisis, Managing Director of JSPL VR Sharma said his company has applied to the State government to provide iron ore for its 9 MTPA pellet plant at Barbil in Keonjhar district under the proactive policy.

With its 6 MTPA capacity steel plant in Angul district, JSPL is ready to pay for the raw material as per the IBM determined cost, he added. Industry bodies like Confederation of Indian Industries, Pellet Manufacturers Association of India, Odisha Sponge Iron Manufacturing Association and others have made representations to the State government highlighting the acute shortage of iron ore for the State-based industries and the skyrocketing rise in iron ore prices.

jsw infra eyes sical logistics tamil nadu iron ore terminal ::

JSW Infrastructure, the unlisted entity of JSW Group, is evaluating options to acquire the iron ore terminal in Tamil Nadu owned by Sical Logistics. If it succeeds, JSW Steel can bring down its logistics cost substantially. The terminal has an annual capacity of 6 million tonnes (mt) and is strategically located at Ennore Port, about 24 km north of Chennai Port. The capacity at the port can be doubled with a minimum investment. In an exclusive interaction with Business Line, Seshagiri Rao, Joint Managing Director and Group CFO, JSW Steel, said: This particular one (Sical Logistics) is interesting to us. We are examining it. Nothing has been decided yet. JSW Steel exports about 3.5 mt of steel and imports close to 25-30 mt (including raw materials) a year. It uses seven ports across the country to bring in raw material and export finished products. It means that the logistics cost is very important to us, Rao said. However, he did not provide any details on the valuation of Sicals iron ore terminal. JSW Group has a steel-making capacity of 14 mt, but does not have iron ore or coal mining rights. With an eye on bringing down logistics cost and doubling its steel-making capacity to 20 mt at Vijayanagar in Karnataka, JSW plans to set up a 500-km slurry pipeline to import iron ore to the plant from a port near Goa. Sical Logistics in a statement said it is not involved in any discussion to sell the terminal to JSW Steel. However, it did not deny discussion with JSW Infrastructure. The Karnataka-based Coffee Day Group acquired a majority stake in Sical in 2011. The port handles over 26 mt of bulk and over 0.5 million TEUS of container cargo annually. Sical, which has a revenue of 800 crore, also provides offshore support services to the oil and gas industry. JSW already has a presence in Tamil Nadu through its subsidiary JSW Steel Salem, which caters mainly to the automotive sector. JSW acquired the sick Salem unit from Tamil Nadu Industrial Development Corporation in 2004 and has managed not only to turn it around but also enhance capacity to 1 mt from 0.3 mt a year with a focus on value-added products.
