18.10.2017The tuffaceous shale is highly enriched in Si (up to 50%) and Al (up to 40%) and, thus, their association with the iron ores is one of the major factors affecting iron ore quality. The ferruginous shale, on the other hand, represents middle or lower shale that mainly occurs as inter-bedded units running parallel to the BIFs sequences.
