Manganese ore reduction - Diamond Shamrock Corporation

Mar 01, 1977· What is claimed is: 1. A process for the pile reduction of higher oxides of manganese in manganese ore, which comprises passing non-oxidizing gas at 700°-1000° C. into and through an initial bed of solid carbonaceous fuel and manganese ore which has been at least partially reduced to MnO, then directing the resulting hot reducing gas mixture into a contiguous layer of unreduced manganese ore ...

Aluminothermic reaction - Wikipedia

Soil contains 0.25% manganese. Tea, wheat and hard-shell fruits also contain much manganese. Manganese-related works include gravel, mining, electric welding, production of dry batteries, and dye industry. In 1774, Gann separated metal manganese; Bergman named it manganese. Manganese can be obtained by aluminothermic reduction of pyrolusite.

Aluminothermic reaction - Wikipedia

Aluminothermic reactions are exothermic chemical reactions using aluminium as the reducing agent at high temperature. The process is industrially useful for production of alloys of iron. The most prominent example is the thermite reaction between iron oxides and aluminium to produce iron itself: . Fe 2 O 3 + 2 Al → 2 Fe + Al 2 O 3. This specific reaction is however not relevant to the most ...
