Metal-to-crystal project, South Africa
Name of the Project
Metal-to-crystal (MTX) project.
Location
Mbombela, in Mpumalanga, South Africa.
Project Owner/s
Manganese Metals Co (MMC).
Project Description
The MTX plant is designed to address the immediate demand for high-purity manganese sulphate monohydrate (HPMSM).
The plant will convert 2 000 t of MMC’s pure manganese metal into 6 000 t of HPMSM using renewable energy.
The MTX process leverages MMC’s existing high-purity electrolytic manganese metal (HPEMM) production and involves the dissolution of a portion of the company’s HPEMM output in sulphuric acid, followed by crystallisation.
The long-term strategy will focus on the more sustainable ore-to-crystal (OTX) process.
This process will use manganese ore as the starting material and, through a combination of chemical and physical processes, remove impurities from the manganese ore to sustainably produce HPMSM crystals, offering a low-carbon footprint product to meet future market
needs.
The OTX process will be built in a phased approach, starting with a 5 000 t/y plant.
This will be followed by an estimated 30 000 t/y plant, targeted beyond 2030.
