It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.

What is Iron Ore? (with pictures) Info Bloom

Iron ore is any rock or mineral from which iron can economically be extracted. It comes in a variety of colors, including dark gray, bright yellow, deep purple, and rusty red. The iron comes in the form of iron oxides such as magnetite, hematite, limonite, goethite, or siderite. Economically viable forms of ore contain between 25% and 60% iron.

Ironstone an overview ScienceDirect Topics

OTHER SEDIMENTARY ROCKS. An ironstone (76) is a sedimentary rock that contains more than 15% iron, which may be present as variable proportions of iron-bearing minerals such as goethite, siderite, and berthierine. Sedimentary ironstones may be hard and calcareous and contain quartz grains, ooliths, pebbles, and a wide variety of macrofossils.
