Hydrogen: The key to a more sustainable

After the hydrogen reduction process, MnO undergoes an aluminothermic reaction (heating MnO in a furnace with aluminum to create a reaction) to produce either pure Mn or manganese–aluminum alloys. If This paper brings an innovative processing route of manganese deep-sea nodules, which results in completely new grades of alloys. Deep-sea nodules were processed by aluminothermic method without the extraction of individual elements, producing complexly alloyed manganese-based “natural alloys”.

FE-SEM image of the Al/MnO 2 thermite before and after

The research about the interaction of Al with MnO 2 in a thermite-like process has shown that the aluminothermic reduction reactions start from above 550 • C to about 900 • C [12, 13]. TheThe stages that cause most of the CO 2 emission in order to produce 1 ton of SS production can be listed as follows: 1.01 ton CO 2 (34.9%) from chromium production, 0.69 ton CO 2 (23.8%) 0.025–0.020% C can be obtained from concentrates Eti Krom A.Ş. containing 47.2% Cr 2 O 3, with 64–66% Cr recovery by aluminothermic A Decarbonization Approach for FeCr Production SpringerLink

An Improved Process for the Production of Low-Carbon

manganese ore melts to form oxides of manganese, iron, silicon and aluminum in the slag. Therefore, the slag can be represented by Mn 3 O 4-Fe 2 3-SiO 2-Al 2 3 system. An exothermic reduction of manganese and iron oxides takes place in the slag.

The aluminothermic reduction process of manganese oxide from different slags by aluminum was investigated using pure Al and two types of industrial Al dross. Two types of MnO-containing slags were used: a synthetic highly pure CaO-MnO slag and an industrial high carbon ferromanganese slag. Mixtures of Al and slag with more Al than theDeep-sea manganese nodules are polymetallic oxidic ores that can be found on a seabed. Aluminothermic reduction is one of the possibilities of manganese nodules processing. This process obtains the polymetallic alloy with a high content of Mn and a varying content of Al, depending on the ratio between aluminum and nodules.Corrosion Properties of Mn-Based Alloys Obtained by Aluminothermic
