The iron ore agglomerates, can then be charged into a blast furnace along with the metallurgical coke to separate the metal from the gangue avoiding the sintering process. Vining said. As there is less waste material to melt, there would also be less metallurgical coke needed in the furnace per tonne of iron metal

Feb 08, 2020 The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional beneficiation techniques used to achieve a suitable

Need for iron ore Beneficiation: Indian hematite ores are typically rich in iron but contain unusually high alumina (as high as seven percent. The current practice of iron ore washing in India results in three products, namely coarse ore lumps directly charged to blast furnace, the classifier fines (3-5% alumina)

Jun 13, 2014 Use of Iron Ore Pellets in Blast Furnace Burden Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-20 mm in diameter by a pelletizer and hardening the balls by firing with a fuel. It is the process of converting iron ore fines into ‘uniformed sized iron ore pellets’ that can be charged directly into a blast furnace
