Process Study of Joda East Washing Plant, Tata Steel

Abstract

Tata Steel is planning for 7.0 mtpa of crude steel product-ion from the present level of 4 mtpa.Accordingly, the iron ore requirement will also increase significantly. More-over, to increase the blast furnace productivity, signifi-cant improvement in the quality of the iron ore is requi-red. To meet a parts of this enhanced requirement of iron ore, both in terms of quantity and quality, a process audit study was undertaken at Joda Iron ore washing plant. The objectives of the study was to assess the process capabilities and to identify the gap areas for a) improv-ing product quality with respect to A1203 content, size distribution, and b) increasing plant throughput. The studies were carried out at three different ore ratios. The performance of the various unit operations and ore ratios on beneficiation products are discussed in this paper.
