What is Electrolytic Manganese Metal (EMM)?
Electrolytic Manganese Metal (EMM) is a kind of high-purity metallic manganese, which is different from ordinary ferromanganese. Its main component is manganese element, with the Mn content ranging from 99.7% to 99.9%, and the impurity content is extremely low. The main impurities include carbon (C), phosphorus (P), sulfur (S), iron (Fe), silicon (Si) and selenium (Se), all of which are strictly controlled within a low range to ensure the excellent performance of EMM.
As a key industrial raw material, EMM has been widely used in many fields due to its high purity and stable chemical properties. In recent years, with the rapid development of new energy and special steel industries, the market demand for high-purity EMM has shown a steady growth trend, becoming one of the most concerned metallic materials in the ferroalloy industry.

2026 Latest Industry News and Price Trends of Electrolytic Manganese Metal
2026 Latest Industry News
In 2026, the electrolytic manganese metal industry is facing a new pattern of supply and demand adjustment, driven by policies, new energy development and resource constraints.
1. Industry Concentration Continues to Improve: Affected by environmental protection policies and energy conservation and emission reduction requirements, small and medium-sized EMM enterprises with backward technology and high energy consumption have been gradually eliminated, and the industry resources have been continuously concentrated to leading enterprises. It is expected that the CR5 (top 5 enterprises concentration rate) of the industry will exceed 60% in 2026.
2. New Energy Demand Becomes a New Growth Pole: With the rapid development of new energy vehicles and energy storage industries, the demand for high-purity EMM in lithium manganese phosphate (LMFP) cathode materials is growing rapidly. It is predicted that the demand for EMM in the new energy field will account for 8%-10% of the total demand in 2026, a significant increase compared with previous years.
3. Supply Side is Constrained by Multiple Factors: Globally, manganese ore resources are highly concentrated in South Africa, Gabon and Australia. In 2026, affected by geopolitics and mine export policies, the supply of manganese ore is relatively tight. Domestically, due to the tight supply of hydropower in the dry season and the continuous tightening of environmental protection policies, the production capacity release of EMM is restricted to a certain extent.
Price Trends and Influencing Factors
The price of electrolytic manganese metal is mainly affected by three core factors: supply and demand relationship, raw material cost and electricity cost. In late January 2026, the domestic EMM market in China has stopped falling and rebounded, with the price returning to the range of 18,000 yuan/ton, driven by the recovery of downstream restocking demand and the rise of raw material costs.
1. Supply and Demand Relationship: The global annual demand for EMM is about 450,000-500,000 tons, of which domestic demand in China accounts for 150,000-200,000 tons. The demand for special steel and new energy fields is the main driving force for price growth.
2. Raw Material Cost: Sulfuric acid and manganese ore are the key raw materials for EMM production. In 2026, the price of sulfuric acid remains high, and the price of manganese ore is supported by tight supply, which has formed a rigid support for the production cost of EMM.
3. Electricity Cost: Most EMM enterprises in China are concentrated in the southern region, which mainly relies on hydropower for production. In the wet season (April-October), the sufficient supply of hydropower reduces the production cost; in the dry season (November-March), the shortage of hydropower leads to the increase of electricity cost, which pushes up the price of EMM.
Preparation Methods of Electrolytic Manganese Metal
At present, the main preparation methods of electrolytic manganese metal include three types: electrolytic process, aluminothermic process and electro-silicothermic process. Among them, the electrolytic process is the most widely used method in industrial production due to its high product purity and stable production efficiency.
1. Electrolytic Process: First, manganese ore is pretreated with sulfuric acid to form a sulfuric acid electrolyte, then the electrolyte is put into an electrolytic cell, and metal manganese is precipitated on the cathode plate through electrolytic reaction. This method has the advantages of high product purity, low impurity content and continuous production, which is suitable for the production of high-purity EMM flakes and powder.
2. Aluminothermic Process: This method uses aluminum as a reducing agent, and uses the chemical heat released by the reduction of manganese oxide to smelt metal manganese. It has the advantages of simple process and fast production speed, but the product purity is lower than that of the electrolytic process, which is suitable for the production of low-purity manganese metal lumps.
3. Electro-silicothermic Process: In an electric furnace, manganese oxide reacts with silicon to generate metal manganese. This method combines the advantages of electric heating and silicon reduction, with stable production process and moderate product purity, which is suitable for the production of manganese metal briquettes and lumps.
