Iron Ore vs. Iron Ore Concentrate
One of the main differences between iron ore and iron ore concentrate is the iron content. Iron ore typically has an iron content of between 56% and 64%, while iron ore concentrate can have an iron content of up to 70%. This higher iron content in iron ore concentrate makes it a more desirable product for steel mills, as it requires less ...
