About TRDDC

About IIME-Mumbai-Pune Chapter (IIME-MPC)

The Tata Research Development and Design Centre (TRDDC), set up in 1981 as a division of Tata Consultancy Services, is today one of India's premier R&D organizations, dedicated to implementing state-of-the-art technological solutions in the Indian industry. TRDDC has a proven record of accomplishment of success in this mission, and has demonstrated its expertise in several successful projects spanning a broad spectrum of industries including minerals and metals

The TRDDC Process Engineering Innovation Lab has executed a number of industrial projects leading to proven/demonstrable benefits to industries such as iron and steel (grinding, flotation, reagent design, pelletization, sintering, direct reduction, annealing, reheating and ladle furnaces, soaking pits, casting, wire drawing, extrusion), nonferrous metallurgical industries (Cu, Pb, and Zn processing and circuit optimization), and cement. It has executed projects related to chemicals (ammonia distillation, lime calcination) and ceramics (dispersion, sintering). The group has also developed a wide variety of software tools including process simulators for assisting plant engineers in optimization on the shop floor and for on-line control.

thThe Chapter started functioning from 14 September 2008 onwards with fifteen life members, has grown up to fifty life members and fifty student members till date. Presently this chapter is hosted at the Department of Earth Sciences, IIT-Powai, Bombay (Mumbai). It has conducted several invited lectures by renowned faculty members and Industrialists from India, on the several aspects of mineral characterization and beneficiation as well as on gemology. It is planning to organize a workshop on "Ore Microscopy" for industry and academic researchers from India, next year.

Scope of the Workshop

India is currently the fifth largest producer of crude steel in the world, with an annual production of nearly 70 million tonnes. The steel production in India is expected to double within the next few years. The annual iron ore production in India will soon be more than 300 million tonnes. With a production capacity of 32 million tonnes per annum and an annual production of over 20 million tonnes, India is also the largest producer of sponge iron (direct reduced iron, DRI). Iron ores and ore fines concentrates are thus needed to meet the increasing domestic demand of blast furnace (BF) and DRI grade products. Considering that the proven reserves of iron ore in India are not large (as compared to the projected demand of this precious commodity in the next decade), the optimum utilization of iron ore resources is an urgent national priority.

The immediate technological challenge facing the industry is to deal with the problem of processing alumina rich iron ore fines and slimes. Additionally, the iron ore industry is beset with the extremely serious problems of shortage of land and water in the states where iron ore deposits are found. It is absolutely imperative that the state-of-the-art mineral processing technology is utilized to achieve the desirable target of zero waste production in the industry for its sustainable growth.

Iron ores are being beneficiated all around the world including until recently at Kudremukh in India. The commissioning of a beneficiation-cum-pelletization plant by Essar Steel recently is an important breakthrough for the industry. It has opened up new possibilities for the iron ore industry in India. The advantages of beneficiating iron ore fines and slimes are obvious: beneficiation will lead to (a) better utilization of natural resources (b) higher mine output in terms of marketable products (c) reduction in the environmental impact of iron ore mining because of reduction in residues (tailings) for storage and disposal and (d) production of high value added products leading to enhanced productivity of sintering or pelletization and reduction operations.

Considering the importance of the topic in the present context, Tata Research Development and Design Centre (A Division of Tata Consultancy Services), in collaboration with IIME, Mumbai-Pune Chapter, is organizing a three-day workshop on the processing of iron ores and ore slimes. The workshop aims to provide a comprehensive discussion on the possible beneficiation strategies for Indian iron ores based on a review of the state-of-the-art technological practices around the world and of the various separation technologies available today relevant to processing of iron ore fines and slimes.

Workshop Topics

The workshop shall cover both scientific and application aspects of various unit operations in iron ore processing. An indicative list of topics to be discussed are presented below. The final list of topics will be decided based on the profile and interests of the participants.

§ Overview of mineralogy and plant practicesØ Mineralogy and flow-sheets of iron ore processing plants in USAØ Mineralogy of Indian iron ores and plant practices

§ Comminution circuitsØ Crushing, grinding and classification

§ FlotationØ Scientific principles underlying flotation of iron ore mineralsØ Review of iron ore flotation operations globallyØ Reagents for iron ore flotation

§ Selective Flocculation and Dispersion of Iron Ores and SlimesØ North American iron oresØ Indian Iron Ore Slimes

§ FiltrationØ Optimization of filtration circuitsØ Effect of water chemistry

§ Pelletization & Sintering Ø Modeling, optimization and control Ø Binders for iron ore pelletization

§ Direct Reduction Ø Modeling & simulation of direct reduction of iron ore by coal in a rotary kilnØ Overview of ITMK3

§ Sustainability and Zero Waste Concepts Ø Concept of zero dischargeØ Eco-cements from industrial and mining wastes

A set of course notes (printed copy) and presentations will be provided on a CD.

Participant Session

A three-hour participant presentations session is planned where participants from different industries are invited to speak on their plant practices and experiences, as well as, to raise important issues related to the workshop theme for discussion.
