Manganese is the 12th most abundant element in the earth's crust. According to the data released by USGS (United States Geological Survey), global manganese reserves are about 570 million tonnes (metal content) with land-based manganese resources distributing irregularly in 2014, and world manganese mine production was estimated to be 17 million tonnes in 2013.

Pure manganese is usually produced by hydrometallurgical and electrolytic processes. According to USGS, world manganese mine production was estimated to be 17 million tonnes in 2013, an increase of 7.6% compared with 15.8 million tonnes in 2012. South Africa was the largest producer in 2013, followed by China and Australia.

Pure manganese used for the production of iron-free alloys is produced by leaching manganese ore with sulfuric acid and a subsequent electrowinning process. Process flow diagram for a manganese refining circuit. A more progressive extraction process involves directly reducing manganese ore in a heap leach. This is done by percolating natural gas through the bottom of the heap; the natural gas

The total tonnage of manganese ore mined is approximately twice the tonnage of beneficiated manganese ore produced because of yields of around 50% after beneficiation. Exports of manganese ores for 2012 totalled 6.7 Mt valued at $1204 million compared to 6.9 Mt valued at $1369 million in 2011. World Ranking.

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 land-based mining production. Once the ore is mined, it's transferred to a processing plant for electrolytic processing or smelting.

Pure manganese is produced by hydrometallurgical and electrolytic processes, while ferromanganese and silicomanganese are produced by the smelting of ores in a blast furnace or, more commonly, in an electric furnace. The latter process, involving the reduction of manganese oxides by carbon, is actually a complex thermodynamic problem.

12.03.2019· Silicomanganese, which contains 65-68% silicon, 14-21% manganese and about 2% carbon is extracted from the slag created during high carbon ferromanganese production or directly from manganese ore. By smelting manganese ore with coke and quartz at very high temperatures, the oxygen is removed while quartz converts to silicon, leaving silicomanganese.

01.01.2012· Silicomanganese is produced by the carbothermic reduction of manganese ores in a submerged arc furnace. It contains 65–68%Mn, 12.5–18.5%Si, and 1.5–3%C. As in chromium ferroalloys, a high silicon content lowers carbon in manganese alloys. The smelting of silicomanganese requires a source for silicon as well as for manganese.

An artificial Mn ore produced as a high grade ore is particularly suitable because of its low impurity level and because all the Mn is present as MnO. The reduction of the higher oxides of Mn is therefore unnecessary.
