Manganese is an essential element in modern industry, especially in steelmaking and ironmaking, where it acts as a key alloying agent that improves hardness, strength, and wear resistance. However, manganese is often produced in powder or flake form, making it difficult to handle and inefficient to add directly into the furnace.
To overcome these challenges, industries have adopted cold briquetting technology to convert manganese powder into dense, durable briquettes. These manganese briquettes not only make transportation and storage easier but also improve smelting efficiency and reduce material loss.
In this article, we will explore what manganese ore powder is, where it comes from, why cold briquetting is necessary, the applications of manganese briquettes, the role of binders in the process, and how Jianjie’s specialized binder solutions help manufacturers achieve stronger, more reliable briquettes.
What is Manganese Ore Powder?
Manganese ore powder is a fine material obtained after crushing, grinding, or processing natural manganese ores or electrolytic manganese metal. It is often generated as a by-product during ore handling, refining, or electrolytic production.
Appearance: typically silver-gray in color.
Properties: known for its hardness and workability.
Challenges: due to its small particle size and low bulk density, manganese powder is difficult to transport, store, and directly apply in metallurgical processes.
This limitation creates the need for briquetting to transform powder into usable, furnace-ready briquettes.
Why Cold Briquetting of Manganese Powder is Necessary

Electrolytic manganese metal (EMM) is usually produced in thin sheets or flakes, which are lightweight and not convenient for direct use in steelmaking. During steel production, adding light manganese flakes is inefficient and leads to handling losses.
To solve this problem, industries developed products such as manganese ingots, manganese pillow briquettes, and manganese balls. Manganese briquettes are formed by crushing, grinding, and cold pressing manganese powder into block-shaped briquettes, followed by drying. These briquettes serve as an efficient manganese alloy additive, offering better density, improved transportability, and easy feeding during steelmaking.
These briquettes are:
- Denser and heavier than flakes, making them furnace-friendly.
- Easier to transport and store without loss.
- More efficient as alloy additives, ensuring consistent manganese input.
Applications of Manganese Briquettes
Manganese Briquettes
Manganese briquettes are widely applied in:
Steelmaking and Ironmaking:
Manganese plays a critical role in steel production as both a deoxidizer and alloying element:
Deoxidizer: Manganese reacts with oxygen in molten steel to form stable oxides, effectively removing excess oxygen. This prevents defects such as gas porosity and improves the purity of steel.
Desulfurizer: Manganese combines with sulfur to form manganese sulfide (MnS), which reduces the harmful effects of sulfur. This improves hot workability, allowing the steel to undergo hot rolling, forging, and welding without cracking.
Alloying agent: By increasing manganese content, steel gains higher strength, toughness, and wear resistance, making it suitable for applications such as construction, automotive, and rail manufacturing.
Compared with light electrolytic manganese flakes, manganese briquettes are heavier, denser, and easier to charge into furnaces, reducing loss during feeding and ensuring more consistent alloying.
Other Uses:
Non-ferrous metallurgy – used in producing manganese alloys.
Chemical industry – raw material for producing manganese compounds.
Battery materials – part of manganese-based cathode materials for energy storage.
By converting manganese powder into briquettes, industries can maximize resource utilization, reduce dust loss, and improve smelting efficiency.
What is The Role of Binders in Manganese Briquetting?
A key challenge in cold briquetting is ensuring that fine manganese particles bind together firmly without disintegration during drying, transportation, or use in high-temperature furnaces. This is where binders play a critical role.
Binders help:
Improve the forming strength of manganese briquettes.
Reduce breakage and powdering rate
Ensure smooth surface and consistent density.
Enhance the high-temperature performance of briquettes in smelting.
Without the right binder, manganese briquettes may crack or disintegrate, leading to operational inefficiencies

Jianjie Binder for Manganese Ore Powder
Manganese Briquettes Using Jianjie Binder
Jianjie Group has developed a series of specialized binders designed for cold briquetting of ore powder and electrolytic manganese powder. These binders offer:
High bonding strength – ensures briquettes remain intact during storage, transportation, and furnace charging.
Customized solutions – the binder can be tailored to meet specific customer requirements, ensuring the best fit for different manganese powder types and production processes.
Superior adhesion – formulated with high-strength components, the binder quickly forms a network structure within the material, providing strong bonding. As a result, the briquettes achieve both high cold strength and hot strength, meeting strict furnace burden requirements.
Jianjie Binder for Ore Powder
Proven efficiency – one ton of binder can produce 35–100 tons of manganese briquettes with a forming rate as high as 98%. The wet briquettes can withstand a 2-meter drop test without breaking, while dried briquettes reach a compressive strength of over 100 kg and can resist temperatures up to 1200°C.
Environmentally friendly – free from harmful additives, safe for steelmaking and environmentally sustainable.
Manganese briquettes are a vital step in transforming fine manganese ore powder into a valuable steelmaking resource. With Jianjie binder, the briquetting process becomes more efficient, cost-effective, and sustainable.
Conlusion
Manganese briquettes have become an essential solution for transforming fine manganese ore powder into a high-value resource for steelmaking, alloy production, chemical applications, and energy storage.
