Manganese ores are located in ore layers of 30-35 cm in the amount of 3-18 pieces and alternate with opoka (a type of carbonate-siliceous sedimentary rock [6]). Carbonate and oxidized layers are located in the upper part, and oxide ones in the lower part; in total, oxide ores – 26.5%, carbonate ores – 45.1%, oxidized – 15% and mixed ...
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

Manganese The Molango mine is a mine located in the center of Mexico in Hidalgo . Molango represents one of the largest manganese reserve in Mexico having estimated reserves of 1.53 bmillion tonnes of manganese ore grading 25% manganese metal.
The ore body was discovered in 1940 by Assmang, and led to the acquisition of a manganese outcrop. The properties on which the ore is situated were subsequently acquired by Assmang, and led to the 1975 commissioning of the Gloria mine (medium grade carbonated ore) as well as the later commissioning in 1972, 1981 and 2004 respectively of the N'Chwaning I, I and III shafts.
The lowest level of the ore zone is a 0.1 to 0.5 metres (3.9 in to 1 ft 7.7 in) layer of massive manganese oxides and hydroxides with some manganese carbonate (rhodochrosite). Above this is the main ore zone, a 3 to 9 metres (9.8 to 29.5 ft) layer of plates of similar minerals between bands of clay, silica and iron bearing material.
Manganese The Gloria mine is a mine located in the north of South Africa . Gloria represents one of the largest manganese reserve in South Africa having estimated reserves of 156.2 million tonnes of manganese ore grading 33% manganese metal.
