Natural manganese dioxide (MnO₂ 70–80%, Mn 45–50%) with a size range of 0.35–0.85mm and bulk density of 1900–2000 kg/m³. Packaged in 25kg bags or jumbo bags up to 1.5mt. Used in batteries, water purification, ceramics, glass, and metallurgy.
Manganese dioxide (MnO₂) is a naturally occurring mineral compound that serves as one of the most versatile industrial oxidants and battery materials available. It occurs in nature as the mineral pyrolusite and is recovered through mining and processing operations. MnO₂ is characterised by its strong oxidising properties, chemical stability, and broad compatibility with industrial processes.
Rawchem supplies natural manganese dioxide meeting 70–80% MnO₂ content and 45–50% Mn, with tightly controlled levels of iron, silica, alumina, arsenic, and moisture. Available in 25kg bags, 1mt, 1.25mt, or 1.5mt jumbo bags.
