Banded Iron Formations (BIF) are in BetterGeo found in masses or single blocks next to other sedimentary rocks like shale, limestone and sandstone, but also near marble. Banded iron formations are one of the new iron ores and replace the former iron ore blocks from Vanilla. By mining banded iron formations you will get iron – an important resource for some of the new recipes! You will be able to track iron by using the magnetic compass. The compass will react when you are less than 20 blocks away from an iron source.
Iron need to be refined in the smeltery.
