Barium is found in most soils and foods at low levels. Barium builds up in fish and other aquatic plants and animals. People are exposed to barium by drinking water and eating food that contains barium, and breathing very low levels of barium in air. Health effects The health problems from different barium compounds depend on how well the compound

The black manganese layer is about 45 meters thick and consists of a 20meterthick ore bed and two lower grade subeconomic beds. The slightly folded layering is shown by the shapes of the various mine . benches. Lighter material in the background is waste that must be stripped to expose the ore bed; this waste material is used as backfill in

More than 25 million tons of manganese are mined every year. Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with landbased mining production. Once the ore is mined, its transferred to a processing plant for electrolytic processing or smelting.
Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. Historically, manganese is named for pyrolusite and other black minerals from the region of Magnesia in Greece, which also gave its name to magnesium and the iron ore magnetite.
2 #0183;#32;Manganese processing, preparation of the ore for use in various products. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 #176;C (2,271 #176;F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such
#0183;#32;Manganese ore and manganese slag (from Mn alloy production) are used in the sinter mix instead of adding them as lumpy ore in the blast furnace. Additives in Blast Furnace. The ideal burden consists of one kind of coke and one kind of selffluxing sinter or
Case Case 1. A manganese mining process project of Xinhai, its main ore is Rhodochrosite and Ca rhodochrosite, then Calcite. Gangue including quartz, chalcedony, carbonaceous and clay, etc. Xinhai contracts the whole designation of the mineral production line, and adopts the process of rough separate the highintensity magnetic ore and concentrate the medium intensity magnetic ore, which
#0183;#32;Problems Related to Manganese Ore Fines Presently, ores below 6mm size generally do not find market in Ferro manganese production. However, a small quantity of fine ores of higher grade is being utilized by Marashtra Electrosmelt Ltd., for production of sinter.
The major problem of low grade manganese ores is The most suitable way of Mn ore fines processing is charcoal was used as the reducing of manganese ore was carried
The main problem of the world''s manganese industry at the present time is the need for highgrade ore deposits which can be exploited relatively cheaply to provide manganese at reasonable prices. With the general drop in grade of the manganese ores available, however, industry has found it

#0183;#32;Santanu Chakraborty, in Treatise on Process Metallurgy: Industrial Processes, 2014. Manganese Ore. Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions.
