Iron ore pricing explained Metal Bulletin

Inter-grade price spreads tend to expand during these times, and high-grade indices such as the MBIOI-65-BZ and Metal Bulletin 66% Fe Concentrate Index (MBIOI-CO) usually extend their premiums to the MBIOI-62 and Metal Bulletin 58% Fe Iron Ore Index (MBIOI-58). Conversely, when margins fall away, mills look to the cheaper low-grade ores to reduce costs and minimize their production rates.
