Manganese is among the world's most widely used metals, ranking fourth after iron, aluminium and copper. Thousands of everyday metallic items require some percentage of manganese in their manufacture.Global production of manganese ore reached 33.7 Mt in 2006. The major suppliers such as China, South Africa, Australia, Brazil and Gabon,provided 80% of the international market.
Worldwide reserves of manganese ore containing >35% Mn were estimated at 440 Mt in 2006. Ukraine, India and Australia account for about 70% of the reserves. The remainder occurs in Brazil, China, Gabon, South Africa, and Mexico.Manganese isessential to iron and steel production.
Large parts of manganese ore is used to manufacture intermediate manganese ferroalloy products and electrolytic manganese for use in dry-cell batteries. Only a small amount of the ore is directly used in the steel making process.Some manganese is recovered through the reprocessing of scrap metals and steel slag, or the materials left over from the steel-making process.
Manganese ore can be mined by open pit quarrying or underground mining method according to ore deposit properties. Mining operations include the mining, crushing, grinding and screening of manganese, and ore handling and processing plant.
The mining of manganese ores is usually operated in open pits. Some ores are upgraded by washing, and undersized ores can be agglomerated by sintering. Several processes have been developed for mining seafloor nodules, but they cannot compete economically with the ready exploitation of high-grade terrestrial deposits.
Most manganese mines are open pit; some are underground. The process of mining manganese involves blasting, crushing, grinding, screening and conveying the crushed ore to following concentration operation to get high grade manganese. The ore is then concentrated at or near the mine site, to increase the percentageof manganese oxide and niobium. The material is concentrated through wet gravity techniques, gravity, electrostatic and electromagnetic processes.
SBM machinery design and develop many new type manganese mining equipment for sale, such as PEW jaw crusher for primary crushing, spring cone crusher and PFW impact crusher for secondary crushing, MTW trapezium mill, ultrafine mill, high pressure mill for tertiary and fine crushing, screening plant, conveying system etc.
With the development of quarrying and mining industries, many new types of mining equipment are designed for various applications. Crushing is the first stage in manganesemining operation, so crushing equipment plays important role in manganese mining plant. Nowadays, tracked mobile crusher machine and screening systems have been used to replace the stationary crushing plants. Due to the advantages of flexibility and mobility, mobile crusher machine can be easily move on the mine and quarry working site, and flexible to transfer between different sites, which saves huge transportation cost for raw materials.
The new complete track mounted mobile crusher machine for manganese mining can be equipped with jaw crusher, impact crusher, cone crusher, vsi crusher and vibrating screen, it is fully adaptable to all mobile crushing needs. The mobile crusher machine for manganese mining can be operated as independent units or as a two or three stages crushing application: from primary to secondary, tertiary and fine crushing. With higher productivity and low operation cost, it is sure that mobile tracked crushing plants will become an even more common sight in quarries and mines around the world in the years to come.
