Used as a precursor in the production of ferrites for electronic components, manganese carbonate serves in the manufacturing of dry-cell batteries, particularly alkaline and zinc-carbon types, where it acts as a depolarizer. It is also employed in the ceramic industry to color glazes and bodies, producing pink to purple shades. In agriculture, it functions as a micronutrient in animal feed and fertilizers to correct manganese deficiency in soils and livestock. Additionally, it is utilized in the synthesis of other manganese compounds and as a catalyst in chemical processes.
