Manganese is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in combination with iron, and in many minerals. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to se, but easy to oxidize.Manganese metal and its common ions are paramagnetic. Manganese tarnishes slowly in air and "rusts" like iron, in water containing dissolved oxygen
In nigeria, Manganese ores usually occur with iron and ores contain between 40% to 70% manganese ores. Niger states,Bauchi state, Benue state and Kebbi state are some of the states the ores are found. Nigeria has over 5,000,000 metric ton of manganese ore reserves.
Manganese phosphating is used as a treatment for rust and corrosion prevention on steel. Depending on their oxidation state, manganese ions have various colors and are used industrially as pigments. The permanganates of alkali and alkaline earth metals are powerl oxidizers.
In biology, manganese(II) ions nction as cofactors for a large variety of enzymes with many nctions.[1] Manganese enzymes are particularly essential in detoxification of superoxide free radicals in organisms that must deal with elemental oxygen. Manganese also nctions in the oxygen-evolving complex of photosynthetic plants. The element is a required trace mineral for all known living organisms. In larger amounts, and apparently with far greater effectiveness through inhalation, it can cause a poisoning syndrome in mammals, with neurological damage which is sometimes
