Manganite is USES Manganite has been used as an ore of manganese in the past. The classic, well-crystallized forms of Manganite from Germany make an important collector's mineral that is highly prized by collectors. MANGANITE (Manganese Oxide Hydroxide) Chemical Formula: MnO (OH), Manganese Oxide Hydroxide. Class: Oxides and Hydroxides. Uses: A minor source of manganese and as a mineral specimen.

Manganite uses

Now its rarity has relegated it to the standing of a minor ore dispite its high manganese content. Crystals are the chief indicator for identification. Manganese may also be used as a finishing coating on objects made of ferrous metals, deposited through a process called phosphating. Manganese salts are dissolved in a solution of phosphoric acid, and the object to be coated is submerged in the liquid. Magnesium is then deposited in a thin layer on the surface.

23 Feb 2018 Here we show how Raman spectroscopy, state-of-the-art THz ellipsometry, and transport measurements are being used to reveal the nature of The mineral was used in prehistoric times as a pigment, by humans, and as a fire starter by Neanderthalers. Manganite is believed to have been used in prehistoric times to start a wood fire. Manganite lowers the combustion temperature of wood from 350 degrees Celsius to 250 degrees Celsius.

Manganite occurs with other manganese oxides in deposits formed by circulating meteoric water in the weathering environment in clay deposits and laterites. It forms by low-temperature hydrothermal action in veins in association with calcite, barite, and siderite. Often associated with pyrolusite, braunite, hausmannite, and goethite.

Example sentences with the word manganite. The most voted sentence example for manganite is The ore generally occurs [15] and Chahara et al. [16] using a method employed for high-temperature superconductors, to which the manganites are structurally related. Optimized ® lms.

More than 30 Mn oxide minerals occur in a wide variety of geological settings. They are major components of Mn nodules that pave huge areas of the ocean floor and bottoms of many fresh-water lakes.

Uses Of Manganese. Manganese is used to produce a variety of important alloys and to deoxidize steel and desulfurize. It is also used in dry cell batteries. Manganese is used as a black-brown pigment in paint. It is an essential trace element for living creatures. It is mainly used to decolourize glass and to prepare violet-coloured glass. 2005 (English) In: Journal of Colloid and Interface Science, ISSN 0021-9797, Vol. 285, no 2, 493-501 Article in journal (Refereed) Published Abstract [en] The co-adsorption of Cd(II) and glyphosate (N-(phosphonomethyl)glycine, PMG) at the manganite (γ-MnOOH) surface has been studied in the pH range 6–10 at 25 °C and with 0.1 M Na(Cl) as ionic medium.
