Manganese: the indispensable metal in modern industry


Manganese, plays a pivotal role in modern economies and industries. This ferrous metal, with its remarkable desulfurizing, deoxidizing, and alloying properties, occupies a prominent position in the realm of metallurgy and beyond. Let’s delve into the multifaceted world of manganese, exploring its critical applications and undeniable importance.

The backbone of steelmaking

At the heart of manganese’s significance lies its indispensable role in steel production. Manganese serves as a key alloying addition in the steelmaking process. Although the amount of manganese consumed to make a ton of steel is small, it is an irreplaceable component in the production of this fundamental material. Steel, the world’s most important engineering and construction material, owes much of its strength and durability to  manganese. It is no exaggeration to say that without manganese, the modern steel industry would grind to a halt.

When added to steel, manganese enhances its properties in several ways. It acts as a powerful desulfurizing agent, preventing the formation of iron sulfide, which can make the steel susceptible to crack and tear during high temperature rolling processes. Additionally, manganese also acts as a deoxidizer, which helps remove oxygen from molten steel during the manufacturing process, preventing oxidation of the metal. Moreover, manganese as an alloying element to steel production, improves steel’s strength and hardness, making it particularly suitable for applications demanding durability and resilience.

No Substitute for Manganese

One remarkable aspect of manganese’s role in steel production is that there are no known substitutes. Unlike other materials that can be replaced or replicated, manganese is irreplaceable in the overall conversion of iron ore into steel. This fact underscores the absolute necessity of manganese for steelmaking, emphasizing its status as an elemental linchpin in industrialized nations.

Beyond Steel

Manganese finds use as an alloying agent with nonferrous metals, such as aluminum and copper, imparting unique properties to these alloys. While steel industry constitutes the largest manganese consumption, it is also important in nonmetallurgical applications.

In the realm of batteries, the main nonmetallurgical application of manganese plays a pivotal role in the production of battery cathodes, primarily in the form of synthetic manganese dioxide. This vital component contributes to the efficiency and longevity of batteries, making it a vital cog in the renewable energy revolution and portable electronics industry.


Manganese also steps into the world of electronics through the production of soft ferrites, particularly manganese-zinc ferrites. These materials are essential in various electronic devices, including transformers, inductors, and microwave components.

Beyond the realm of industry, manganese serves a critical role as a micronutrient additive in fertilizers and animal feed. Manganese sulfate and manganous oxide are essential components that ensure the health and growth of crops and livestock.

In the sphere of water treatment, manganese compounds like potassium permanganate and manganese dioxide are employed as effective water purification chemicals. They assist in removing impurities and contaminants, safeguarding public health and the environment.

Furthermore, manganese dioxide finds its way into various chemicals, serving as a colorant for automobile undercoat paints, bricks, frits, glass, textiles, and tiles. Its versatile nature and ability to impart vibrant colours make it a sought-after additive in the manufacturing of numerous consumer products.

Manganese is a strategic raw material

Manganese, recognized as a strategic raw material, has gained even more prominence due to the increasing supply risk at the extraction stage. This heightened risk was exacerbated by a significant drop in domestic supply, plummeting from 32 tons to just 10 tons, attributed in part to production halts in Bulgaria and Hungary. This decline has pushed industrialized nations towards an increased reliance on imports, particularly from South Africa, accounting for 41% of imports (compared to 33% in 2020), and Gabon, contributing 39% (up from 26% in 2020). As such, the economic importance of manganese within the European Union has always remained exceptionally high, underscoring its role as a linchpin in both steelmaking and battery production, and the necessity of securing its supply chain for continued industrial growth and innovation.

Manganese may often work quietly in the background of our modern industrialized world, but its importance is undeniable. From fortifying steel to powering batteries and enhancing agricultural yields, manganese is a versatile and irreplaceable element that continues to shape the trajectory of industry and innovation. As we look to the future, it’s clear that this unassuming metal will remain at the forefront of technological advancements and industrial progress.
