Metallurgical Research Institute



Metallurgical Research Institute

The Metallurgical Research Institute (MRI) undertakes research and development in mining, metallurgical, materials, foundry and other forming technologies, and to develop and commercialize a portfolio of bankable projects in the specialized area of metallurgy.

The Goals of the Institute

Providing technical consultancy and training services to the mining and metallurgical

  • Assaying and analytical services for base, minor, platinum group metals (PGMs) and
    precious metals, ferro-alloys, coals and metallurgically complex (refractory) ores and
  • Pre-feasibility and due diligence studies in mineral and extractive metallurgy projects.
  • Metallurgical accounting, process audits, trouble-shooting and optimization of mineral
    processing circuits
  • Value addition processing and beneficiation of local mineral and energy resources
  • Development, production and supply of mining, mineral processing, automotive and
    agricultural equipment and spares.
  • Development and production of refractories.
