:: allmineral Forges Ahead in Iron Ore Beneficiation in Indian Markets

Together with Indian partner Hari Maschines Ltd, allmineral has managed to convince yet another major Indian company of the quality and performance of the "made in Duisburg" processing plants. Jindal Steel & Power Limited (JSPL) has ordered a total of 14 machines to expand an exiting site for haematite iron ore beneficiation in the Sarda Mines in the Indian province Orissa.

Eleven air-pulsed alljig®jigging machines and four gaustec®-3600 magnetic separators will allow JSPL to process low grade iron ores into products with high iron content suitable for the market. In the 1500 t/h plant in the »Sarda Mines« , five alljig® G-2200 and six alljig® F-2500 will be used to process grain sizes between 5 to 30 and 1 to 5 millimetres respectively. The gaustec® magnetic separators with a throughput of 200 tonnes per hour each will upgrade the material with a grain size below one millimetre.

The plant expansion should be completed third quarter 2009. In this project also, allmineral will be working together with Hari Machines Ltd.: the Indian partner will manufacture the 14 units while allmineral will supply core components from Germany.

"We were involved in the process development from the start on and developed the concept for the new plant together with the client based on numerous pilot tests", allmineral CEO Dr. Ing. Heribert Breuer said. Two issues were critical for JSPL: to set up a beneficiation plant with a maximised product yield and to not only produce products with high iron content but also those with a reduced Al2O3 content. The rejects from the jigs and the first WHIMS stage will be reprocessed in the next sorting step after recrushing resp. regrinding.

The Lump and Sinterfeed products will serve the Jindal blast furnace plants. The concentrate with a grain size of less than one millimetre, after further grinding (< 40µm), will be used on site in a 4-million tpa. pellet plant, which is under construction. Depending on feed quality, the total production for the plant will be between 8 and 9 million tonnes per year.

The modernisation of the plant in the »Sarda Mines« is part of a multi-billion investment programme with which JSPL is expanding the capacity of its steel plants, power stations and mines. The company, which was founded in the early 1950s, has an annual turnover of about 4 billion USD , is the third-largest steel producer in India. JSPL mines coal and iron ore in India, the USA, Indonesia and, soon, also in Bolivia. It operates power stations and produces a wide range of steel products. The company employs some 20,000 staff around the world.
