Currently used as a field-term unidentified massive hydroxides and oxides of iron, with no visible crystals, and a yellow-brown streak. 'Limonite' is most commonly the mineral species goethite, but can also consist of varying proportions of lepidocrocite, hematite and/or maghemite, along with impurities of other minerals such as quartz and clay s.

Pig Iron, on the other hand, is more brittle, has a higher carbon content, and is less pure. Another key difference between Sponge Iron vs Pig Iron is their cost. Sponge Iron is cheaper to produce as it does not require coke, which is an expensive raw material used in the Pig Iron manufacturing process. However, Pig Iron has a lower melting ...

Massive Goethite and Limonite can be indistinguishable. Limonite forms mostly in or near oxidized iron and other metal ore deposits, and as sedimentary beds. Limonite has been known to pseudomorph other minerals such as pyrite, meaning it replaces a crystal of pyrite with limonite but keeps the shape of the pyrite crystal.

Limonite is always fine-grained and usually quite earthy. It may be crudely fibrous, oolitic, botryoidal or stalactitic. Its hardness is usually around 4, but can be soft enough to scratch with a fingernail. It is yellow, orange or brown and has a yellow to brown streak. Some of it is described as "ocher", some as "bog iron ore" some as "gossan ...

Limonite (pronounced "lime-on-ite") is an iron ore similar to the more well-known iron oxides haematite and magnetite. It often forms as existing deposits of these other minerals react with water in an oxidation reaction, turning the iron oxide into iron oxide-hydroxide. This interrupts the regular crystal structure and opens up microscopic ...

This is in addition to its use as an ore of iron; limonite can contain up to 59.8% iron(3). Whilst this value isn't as high as magnetite or, in particular, hematite(4), it remains a viable ore of the highly economically important metal. The terms yellow ochre and limonite will be used interchangeably throughout this article.
