Reduction of Oxides and Reduction Smelting SpringerLink
In the Wiberg–Soderfors process [], sponge iron is produced in a shaft kiln at 1100 °C by passing water gas (H 2 + CO) over iron ore or concentrate.As there is no liquid slag formation at this temperature, the impurities are not separated. The resultant solid product containing the gangue oxides named “sponge iron” is subsequently melted in an 2 天之前The beginning of the Manganese ore processing involves a multistage crushing workflow. From there, the production of ferromanganese, the manganese ore is mixed with iron ore and carbon and then reduced either in a blast furnace or in an electric arc furnace.

Manganese is important to Australia’s critical minerals strategy. Manganese is used in a variety of industries, including in manufacture of renewable/dry cell batteries, wind turbines and aluminium steel alloys. Western Australia has produced about 14.8 Mt of Mn ore since 1948 (GSWA, 2021) and hosts several large Mn projects at various stagesNitrided ferromanganese is an additive agent for nitrogen in certain grades of steel. The production process is based on the high affinity of manganese for nitrogen in the solid state. The compacts of medium carbon ferromanganese or manganese metal powders are reacted with nitrogen at 600–1000 °C.Ferromanganese an overview ScienceDirect Topics
