The plant trials were performed at Tata Steel's iron ore mines and concentrator at Noamundi. The slime sample was withdrawn periodically from the hydrocyclone over flow (COF), that is, the tailings of the beneficiation plant as schematically shown in Fig. 1. The fresh slimes sample was stored in a kL tank for a set of continuous scale tests.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

The majority of European steel (60%) is made via the primary route. It involves processing iron ore to produce iron sinter or pellets, and then melting these in a blast furnace (BF) with coke to make pig iron. This is processed in a basic oxygen furnace (BOF) to create steel. The rest of Europe's steel comes from the secondary route.
