To meet this requirement, ores are often beneficiated at the mine to separate the iron oxides from the impurities, producing a concentrate that is then pelletized. This process is already routinely done globally, favoring locations with high-grade ore such as Canada and Brazil, but also with low-grade ore, such as the 20–35 percent iron ore ...
