Iron Ore Fines 62% Fe — Blast Furnace & Sinter Plant Feed
Iron ore fines at 62% Fe minimum feed blast furnace and sinter plant operations at steel mills across the Middle East, South Asia and Mediterranean. Sized 0–10 mm with controlled silica (4.5% max) and alumina (2.5% max) to optimize slag volume and coke rate in the furnace. Moisture capped at 8% for safe bulk vessel transport under IMSBC Code requirements. From 25,000 MT.

Vessel Logistics
Iron ore fines require careful moisture management — cargo liquefaction risk under IMSBC if moisture exceeds transportable moisture limit (TML). Independent surveyor certification of moisture and TML before loading is standard practice. Gearless bulk carriers 50,000–180,000 DWT on FOB/CIF routes from Black Sea, India and Middle East origins.
FAQ
What is the difference between 62% Fe fines and 65% Fe concentrate?
Higher Fe grade reduces slag generation and coke consumption per tonne of hot metal. 62% Fe fines trade at discount to 65% Fe index; mills blend lower-grade fines with pellets to achieve target furnace burden chemistry.
Why is alumina limited to 2.5% max?
Alumina increases slag volume in the blast furnace, raising coke rate and reducing productivity. Mills in the Gulf typically specify Al₂O₃ below 2.5% and prefer below 2.0% for efficient operation.
Are iron ore fines subject to liquefaction risk during shipping?
Yes. Fines with moisture above the certified TML can liquefy during ocean transit, causing cargo shift and vessel instability. Pre-loading moisture certification and can-test are mandatory under IMSBC Code for Group A cargoes.
