Manganese does not present a danger to human health, nor for the environment but it is unpleasant. In fact, the water gets a black color and a metallic taste. Similar to iron, the manganese removal by physical-chemical way, can be carried out by the oxidation of Mn 2+ in Mn 4+, which precipitates then in manganese dioxide (MnO 2).

Manganese is a greyish-pink metal. It resembles iron in its physical appearance. It is brittle and hard. Manganese has a paramagnetic nature. when exposed to air and moisture, it undergoes slow oxidation that leads to rusting. Manganese is a dense metal, with a density of 7. 43 g.cm- 3 at room temperature.

Production & processing. The alloying and processing methods for alloy steel depend on the desired result. The required combination of elements is first melted together in a furnace at over 1600°C for 8 to 12 hours. The steel is then annealed at over 500°C in order to remove impurities and to alter the physical and chemical properties [4].

Isobel Mc Dougall, in Handbook of Ferroalloys, 2013. 4.2.2 Sintering of Manganese Ore. The sintering process employed for manganese ore and the siliceous ores used to produce silicomanganese results in partial reduction of MnO 2, Mn 2 O 3, and Mn 3 O 4 in the ore to MnO by reaction with carbon in addition to agglomerating the fine ore and coke.

Pure Manganese used for the production of iron-free alloys is produced by leaching manganese ore with sulfuric acid and a subsequent electrowinning process. The treatment of the Manganese ore should be designed to produce a maximum amount of the Manganese in a coarse form which will be marketable without the further and high cost of nodulizing or sintering.

For manganese dopant, this was due to the substitution of lighter atomic mass of manganese as compared to tellurium. In contrast, the inclination in the density value was caused by the excess oxygen due to the presence of TeO 4 functional groups as well as by the addition and substitution of heavier strontium atomic mass (87.62 g/mol), as compared to the other present atoms found in the glass
