01
The refining system starts offevolved with high-grade ore, mined in the Kalahari.
02
The ore is milled to a powder.
03
Then it undergoes calcining in rotary kilns, to be decreased to a soluble form.
04
The decreased ore is dissolved in acid solution.
05
Solution purification – precipitation of impurities in two thickener stages, accompanied through filtration in clarifilters.
06
Sulphur dioxide, and now not selenium dioxide, is brought to the purified answer earlier than electrolysis can take place.
07
The solution is then fed into the electrolytic cells, the place electric powered present day reasons the pure manganese to plate on the cathodes.
08
The plated manganese is stripped from the cathodes, washed, dried and degassed. This metallic is manganese in its purest, cleanest form. Depending on the person client requirements, the metallic is then processed similarly (e.g. milled to powder) and packaged for shipment.
09
Sulphuric acid, shaped at the anodes, is re-cycled returned to the dissolution process.
10
The strong residue final after dissolving the manganese is filtered to get better manganese- and ammonium sulphates to acquire a dry cake for disposal.
11
The recovered answer is again to the dissolution.
12
The dry cake is transported to Kingston Vale. MMC holds approves to function a hazardous landfill facility here. The Kingston Vale landfill graph consists of liners with leakage detection and trenches to gather all run-off and leachate.
13
After collection, the liquid is again to MMC’s plant and exceeded thru the effluent remedy plant. All different liquid effluents from somewhere on the MMC site, together with contaminated runoff from rainwater, are additionally cleaned in the effluent cure plant.

To tackle the developing demand for manganese in the battery industry, MMC developed two proprietary techniques for producing High Purity Manganese Sulphate Monohydrate (HP MSM):
Metal to Crystal (MTX): This system builds on our current HP EMM manufacturing by using dissolving a element of our output—produced the usage of a hundred percent renewable electricity—in sulphuric acid, and then crystalising it to create HP MSM crystals. The MTX method offers MMC a good sized speed-to-market benefit and the flexibility to scale our production in line with demand from pCAM producers for non-Chinese sustainable HP MSM.
Ore to Crystal (OTX): This long-term, sustainable, and lowest value strategy will make use of manganese ore as the beginning cloth and via a mixture of chemical and bodily tactics dispose of impurities from the manganese ore to produce HP MSM crystals at giant scale, presenting an even lower-carbon footprint product to meet future market needs.
We are presently in the early tiers of developing a 6,000-tonne per annum business HP MSM plant in Mbombela, South Africa, the usage of the MTX process, scheduled to start manufacturing in H1 2026. This brownfield enlargement at our present HP EMM website will considerably beautify our production capability and market presence.
We purpose to furnish our clients with a safer, cleaner, greater sustainable Manganese Sulphate product whilst additionally imparting them the chance to keep away from dealing with international locations that have excessive tiers of geopolitical tension, unrest and lack of transparency.
