High Purity Manganese Sulphate to Power the Battery Revolution

High Quality Manganese Sulphate for Agriculture

Overview of Mn Energy

Mn Energy (MNE) was founded by a group of manganese sulphate industry specialists. In early 2018 we successfully completed a test carried out by CSIRO to produce high purity and high value Manganese Sulphate from low cost, low grade Manganese ore.  Our aim is to be the first producer of high purity Manganese Sulphate (MnSO4) in Western Australia, and a direct supplier to both the global battery cathode market and the Australian agricultural/fertiliser industries.

Battery Grade High-Purity Manganese Sulphate

High Purity Manganese Sulphate is used in the cathode structure of lithium-ion batteries, together with other minerals such as lithium, nickel and/or cobalt. Our vision is to manufacture the highest purity of manganese sulphate using our proven purifying technologies. Mn Energy’s unique purification process ensures we meet our highest purity goals of 99.99%, as required for the battery market. Additionally, Mn Energy’s processes will manufacture the highest quality of Nickel / Manganese / Cobalt Oxide (LiNiMnCoO2) together with Lithium Manganese Oxide (LiMn2O4). These two cathode structures are some of the most used due to Manganese’s lower cost and reliability.

The Lithium-ion Battery Evolution

Mn Energy is on track to be Australia’s first MnSO4 producer, servicing a rapidly growing international demand for rechargeable batteries.

Mn Energy has industry-leading consultancy teams supporting the business and technology growth that will take us into the next phase of the battery industry’s evolution.  Our current board, management & shareholders have over 10 years’ experience in the manganese sector having previously been founding directors & shareholders of Auvex Resources Limited, a manganese miner & producer, now part of the Mineral Resources Group.

Mn Energy are members of the International Manganese Institute, the Future Battery Industries Cooperative Research Centre bid and part of the WA State Government Lithium & Energy Metals Industry Consortium.

High Quality Manganese Sulphate for Agricultural Use

We are developing an economical and environmentally friendly process to concentrate low quality Manganese ore into fertiliser and feedstock for Australian agriculture.  Currently Australia imports 30,000 tonnes of Manganese Sulphate per annum for agricultural use.  MNE can offer a cost competitive product locally manufactured product.

A Brighter, Cleaner Future for Manganese Sulphate

We aim to reduce our carbon footprint by making our process as clean as possible. This is achieved by utilising other companies waste products from our local area and ensuring that our by-products are usable and sale-able for the other industries. Our plant, to be located in the East Rockingham Strategic Industrial Area, will produce 40,000 tonnes of MnSO4 at various graded qualities for world markets.

Specialists In Manganese Sulphate


Ore Supply

Mined locally from the Pilbara region in Western Australia.

Ore Supply

Low-grade manganese ore is utilised in MNE’s process to produce manganese sulphate. Previously uneconomical for manganese miners due to shipping expenses, it is the ideal feed for our process.
