Used as a precursor in the production of ferrites for electronic components, manganese carbonate serves as a key raw material in manufacturing dry-cell batteries, particularly alkaline and zinc-carbon types. It acts as a source of manganese in fertilizers and animal feed supplements to correct manganese deficiencies in soil and livestock. In the glass and ceramic industries, it functions as a coloring agent, imparting pink, brown, or purple hues, and helps decolorize glass by counteracting iron impurities. It is also employed in the synthesis of other manganese compounds, such as manganese dioxide, and in some catalytic applications, as well as in the production of certain pigments and coatings.
