Metallurgical Research Institute (MRI)

About the 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 industry.
    • Assaying and analytical services for base, minor, platinum group metals (PGMs) and precious metals, ferro-alloys, coals and metallurgically complex (refractory) ores and concentrates.
    • 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.
  • Institute Divisions
