Grange Resources

The Savage River magnetite iron ore mine, 100km southwest of the city of Burnie, produces some of the highest iron-concentrated magnetite in the country with minimal impurities. Port Latta 70kms northwest of Burnie is Grange Resources' wholly owned pellet plant and port facility at Port Latta - producing over 2.2 million tonnes of premium quality iron ore products annually.16.3.1.1 Background. In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based.

Ore Pellet

For example, in blast furnace iron making, Fig. 5.1, iron oxide in the form of lumpy ore, sinter or pellet along with coke and limestone, are charged on the top of the furnace continuously. The charge slowly moves down and hot reducing gases produced by burning of coke in front of tuyeres move up through the bed of solids and finally escape through the gas outlet. · 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 low-grade 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 …
