3rd School on Manganese Ferroalloy Production

Date 24 June 2020
- 25 June 2020
Location Kathu, Northern Cape
Resources Manganese-2020.pdf

South Africa has the largest land-based manganese ore deposit in the Kalahari Manganese Field. Although the country primarily exports the ores it also beneficiate it locally by producing manganese ferroalloys.

In order to support the smelters, and foster collaboration between researchers in the field, the SAIMM hosted in the past two Schools on Manganese Ferroalloy Production. As a result of the workshop included in the program of the 2nd event, Project PreMa was identified. PreMa aims at demonstrating an innovative suite of technologies, involving utilization of industrial off-gases and solar thermal energy, to reduce energy consumption and CO2 emissions from manganese production as a means to obtain sustainable production of Mn-alloys and steel.

The project is funded by the Horizon 2020 program of European Union, and European and South African industrial partners. The conversation around the topic will continue at the 3rd School on Manganese Ferroalloy Production which will include a visit to some of the mines in the Kalahari Manganese Field. An open call for abstracts will follow in due course.

Target Audience

  • Local and international delegates from the manganese ferro-alloy industry or those who support them
  • Existing and potential future industry role players
  • Engineering companies
  • Research/academic institutions
  • Companies providing funding for new manganese projects


  • To create an opportunity for researchers and operators, to update their knowledge on the production of manganese ferroalloys.
  • To create a platform where researchers and operators can exchange views on the best practices for the production of manganese ferroalloys.
  • To create a platform for the PreMa project to disseminate the preliminary results of the collaborative research and obtain inputs from parties outside of the consortium.
  • To further enhance collaboration between parties.


  • Commercial production processes including overviews of manganese production in South Africa and in Europe as well as introductions to potential new projects.
  • Process fundamentals including fundamental thermodynamics, slag fundamentals, and reaction kinetics.
  • Operational aspects including raw materials, pre-reduction zone, cokebed zone, lining concepts, energy consumption, electrical current paths and resistance in furnace, and environmental considerations.
