What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.
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 the result of decomposition of iron minerals, where water, carbon dioxide, humus acid and oxygen react with the minerals and gradually transform them into limonite.
Limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)·nH2O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually
Ochre (/ ˈ oʊ k ər / OH-kər; from Ancient Greek: ὤχρα, from ὠχρός, ōkhrós, pale) or ocher (American English) is a natural clay earth pigment which is a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced by this pigment, especially a light brownish-yellow.
In some cases, limonite can even be sacial, being converted readily into other compounds such as nanoparticles. For the Synthesis of Iron Nanoparticles Iron nanoparticles have been employed for myriad tasks in the last two decades, with applications across the catalytic spectrum, they are prized for their surface area to volume ratio.

McCoy Mountains Limonite Cubes. Text by Delmer G. Ross - Photographs by Karen A. Ross "Limonite" is a term used to describe any iron hydroxide that has not been more exactly identified through the use of elaborate chemical analysis. Obviously, then, there are various different kinds of limonite.
Goethite, a widespread iron oxide mineral [α-FeO(OH)] and the most common ingredient of iron rust. It was named in 1806 for J.W. von Goethe, a German poet and philosopher with a keen interest in minerals. The name was originally applied to lepidocrocite [γ-FeO(OH)], a less common mineral with the s
Roasting the limonite changed it partially to hematite, producing red ochres, burnt umbers and siennas. Limonite can be used in the production of iron and steel but this is much less common than for both Hematite and Magnetite. It has been known to contain Nickel, however, and some producers have used the ore to make stainless steel.
Limonite Ingots are a metal that can be used in several crafting recipes. It can be smelted from Limonite Ore and crafted into blocks. Limonite is regularly used in the crafting recipe of Robin's suit and other characters. Limonite can be used in these following recipes:
Currently used for 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, hisingerite, pitticite, jarosite group species, maghemite, hematite, etc.
Jan 28, 2014· Limonite is very common worldwide with deposits notable in China, Italy, Spain and the US. Limonite can be used in the production of iron and steel but this is much less common than for both Hematite and Magnetite. It has been known to contain Nickel, however, and some producers have used the ore to make stainless steel.

Limonite is an ore consisting in a mixture of hydrated iron(III) oxide-hydroxide of varying composition. The generic formula is frequently written as FeO(OH)·nH 2 O, although this is not entirely accurate as limonite often contains a varying amount of oxide compared to hydroxide.
The limonite accumulates so fast in some places that a lake bottom may be cropped again after a number of years, as at Radnor Forges, Quebec.

Feldspar - Feldspar - Uses: Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldspar-rich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.
Limonite definition is - a native hydrous ferric oxide of variable composition that is an ore of iron.
Some sedimentary rocks and their metamorphosed products contain such high percentages of hematite that they have been recovered as iron ore. Hematite may also be used as a polishing powder and as a paint pigment. Limonite. Limonite is the catchall name widely applied to hydrous iron oxide minerals.
Limonite is not a true mineral but a mixture of similar hydrated iron oxide minerals. Most of limonite is made up of Goethite. Massive Goethite and Limonite can be indistinguishable. Limonite forms mostly in or near oxidized iron and other metal ore deposits, and as sedimentary beds.
