How Is Iron Ore Found? Iron ores are rocks from which metallic iron can be economically extracted.Most deposits of iron ore in the world are found in rocks known as banded iron formations (BIFs). These are sedimentary rocks that have alternating layers of iron-rich minerals and a fine-grained silica rock called chert.

Some argued that formation of Shilu iron ore is mainly due to multiple remodeling and enrichment that is, the formation of iron ore deposits is affected by "volcano-sedimentary metamorphism + structural transformation + hydrothermal". A total of 38 iron ore bodies have been found, most of which are yielded in the 6th layer of Shilu Group. ...
