In the glass industry, manganese compounds are used for two effects. Manganese(III) reacts with iron(II) to reduce strong green color in glass by forming less-colored iron(III) and slightly pink manganese(II), compensating for the residual color of the iron(III). [45] Larger quantities of manganese are used to produce pink colored glass.
As a result, the remaining slag has a concentration of 30% to 50% of the manganese. This is then reprocessed with quartzite to make silicomanganese alloys. The resultant discarded slag has a manganese content of less than 5%, increasing the yield. As a result, this method is used more often in industry.
Selenium, like manganese, can be used in small concentrations to decolorize glass, or in higher concentrations to impart a reddish color, caused by selenium nanoparticles dispersed in glass. It is a very important agent to make pink and red glass. When used together with cadmium sulfide, [9] it yields a brilliant red color known as "Selenium Ruby".
The deposit was discovered in 1879 by the Georgian poet Akaki Tsereteli [7] who explored the area in search of manganese and iron ores. After other explorations it was discovered that there are several layers of manganese oxide, peroxide and carbonate with thickness varying between 0.2 m (0.66 ft) and 16 m (52 ft).
The nickel content of individual Chinese products varied from about 1.6% to as much as 80%, depending upon customer end use. [2] In the United States, the steel industry accounted for virtually all the ferronickel consumed in 2008, with more than 98% used in stainless and heat-resistant steels; no ferronickel was produced in the US in 2008.

This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO 2 is for dry-cell batteries, such as the alkaline battery and the zinc–carbon battery. [4] MnO 2 is also used as a pigment and as a precursor to other manganese compounds ...
Below is a list of commonly used metallic deoxidizers: Ferrosilicon, ferromanganese, calcium silicide - used in steelmaking in production of carbon steels, stainless steels, and other ferrous alloys; Manganese - used in steelmaking; Silicon carbide, calcium carbide - used as ladle deoxidizer in steel production
Manganese is a chemical element with the symbol Mn and atomic number of 25. It is found as the free element in nature (often in combination with iron), and in many minerals. The free element is a metal with important industrial metal alloy uses. Manganese ions are variously colored, and are used industrially as pigments and as
