Used as an alloying agent in steel production to improve strength, toughness, and wear resistance. It also serves as a desulfurizer and deoxidizer in steelmaking processes.

Essential in manufacturing aluminum-manganese alloys for beverage cans, automotive parts, and other applications due to its enhancement of corrosion resistance, durability, and formability.

Employed as a raw material in the production of dry-cell batteries, such as alkaline and zinc-carbon types, where manganese compounds derived from it provide electrochemical properties.

Acts as a precursor for catalysts in chemical reactions and in electrolytic processes for the production of oxygen and chlorine.

Used as a source for micronutrients in fertilizers and animal feed to support plant growth, photosynthesis, enzyme function, and animal health.

Found in the production of pigments for ceramics and glass, providing purple, pink, or brown colors; also aids in decolorizing glass by reducing bubbles.

Additionally, utilized in paints and coatings as a drier to accelerate drying, particularly in oil-based formulations.
