Comminution is an essential step in processing itabirite ores, given the need to liberate silica and other contaminants from the iron minerals for downstream concentration and then pellet feed production. In general, these ores in Brazil are not particularly hard to crush and grind, but both capital (CAPEx) and operating (OPEx) expenditures in this stage of preparation can be critical for the

On an average global basis, iron ores tend to decrease in Fe grade over time. With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if high-grade concentrates are desired.
