Used extensively for television circuit boards and drycell batteries, manganese can make electronics more resilient. The next generation of rechargeable batteries is likely to use more manganese. Where does manganese come from? Although manganese is abundant in the Earth's crust, 80% of the world's supply comes from South Africa.
Physical properties Manganese is a silverygray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. [7] Manganese metal and its common ions are paramagnetic. [8] Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen. [citation needed] Isotopes
Domestic Production and Use: Manganese ore containing 20% or more manganese has not been produced domestically since 1970. Manganese ore was consumed mainly by six companies with plants principally in the East and Midwest. Most ore consumption was related to steel production, either directly in pig iron manufacture or ... dry cell batteries ...
Manganese dioxide, besides being a useful pigment, is a catalyst and a component of certain dry cell batteries. Potassium permanganate is a potent oxidizer and disinfectant. Manganese (in the form of manganese ions) is an essential trace nutrient in all known forms of life. On the other hand, excess manganese is toxic. Occurrence
Dry cell batteries are a common type of power source. Tiny dry cell batteries are sometimes called button batteries. This article discusses the harmful effects from swallowing a dry cell battery (including button batteries) or breathing in large amounts of dust or smoke from burning batteries. This article is for information only.

Modified date: 23/04/2023. Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silverygray metal that is commonly found in the Earth's crust. Manganese is an essential trace element that plays a crucial role in many biological processes, including metabolism, bone formation, and antioxidant function.
Manganese dioxide is strategically significant for the production of drycell batteries. Nonmetallurgical uses of manganese include: plant fertilizers, animal feed, and colorants for brick. In 2019, the value of domestic consumption, estimated from foreign trade data on a manganesecontent basis, was about billion (USGS, 2020).
Manganese is an important metal mineral and is widely used in metallurgy and chemical and defense industries [1,2,3].It is usually used to produce ferromanganese, nonferrous alloys [4, 5], dry batteries, coatings, cells, fertilizers, and fine chemicals [].At present, the annual consumption of manganese continues to grow worldwide.
