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. …

Guide to Modern Smelting Processes – T09-002 5 Iron Smelting: Iron smelting involves reducing iron ore, typically hematite or magnetite, in a furnace. The high temperatures required (over 1500°C) posed significant challenges. Early iron smelting was accomplished using charcoal- fueled furnaces known as bloomeries.
