04/11/2015  On the other hand, the imported ores had much higher iron content, which is why they were imported in the first place, and most had/have some treatment or 'benefication' carried out at the point of extraction. There's no point in shipping 100,000 tons of ore from Australia if only 50,000 tons of it is iron. So, imported ores are denser and are often treated to improve the iron
