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 ...

Blast furnace The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

The present study presents the effect of pH reduction in iron ore slurry for an iron ore filtration process. A reduction on moisture content and increase on filters throughput was proposed by the pH modification. The experimental procedure included bench scale tests and industrial scale up of the observed results. Additionally, Langelier's saturation index was applied to determine the ...

HYFOR (Hydrogenbased FineOre Reduction) is a novel direct reduction process for iron ore fines concentrates from ore beneficiation, developed by MHI Group company Primetals Technologies. It builds on fluidizedbed reduction technology, does not require any agglomeration (such as sintering or pelletizing), and uses on 100% hydrogen as a feedstock.
