The Manganese is a metallic element that occurs naturally in rocks and soils and is found in small quantities in living organisms. It is vital for plant growth, supporting key enzyme processes that help convert sunlight into usable energy through photosynthesis. In agriculture, manganese-rich soil promotes healthier, more productive crops. Humans also rely on manganese as a trace nutrient, helping maintain proper metabolism, bone strength, and antioxidant defenses. Although only small amounts are needed, they play an important biological role.

Industrial uses of manganese are dominated by steelmaking, where manganese acts as both a purifier and a strengthening agent. It removes unwanted sulfur and oxygen from molten iron, allowing steel to become tougher and more resistant to stress. The metal is also used in batteries, pigments, ceramics, and glass industries. Manganese dioxide, for example, is a key component in alkaline and zinc-carbon batteries. In glassmaking, it helps control color and remove impurities. As industries continue to innovate in energy storage and sustainable materials, manganese remains a key contributor to technological progress.
