Modern mining technology needed for SA to remain a key supplier of critical minerals

The CSIR contributed to the South African Critical Minerals Strategy, which focuses on how the country can remain a competitive global supplier of critical minerals such as chrome ore, iron ore, copper, manganese, coal and platinum group metals (PGMs). Africa is richly endowed with these resources, which are essential to sectors such as renewable energy, electronic manufacturing and defence. The global energy transition is driving increased demand for the extraction and processing of critical minerals. The strategy aims to leverage South Africa’s natural resources in a manner that promotes inclusive growth, industrial development, job creation, and economic transformation. It underscores the importance of infrastructure development, skills enhancement, research and innovation, and international partnerships to ensure that our mineral wealth becomes a catalyst for long-term prosperity.

Areas of work

Vuyani Jarana
Responsible mining

The CSIR supports mining companies in transitioning to more responsible mining strategies, ensuring that minerals are extracted with future sustainability in mind, that community rights are respected, worker safety prioritised and long-term economic benefits are promoted. It recognises the importance of custodianship of mineral resource.

Nomsa Dlamini
Circular economy

Our studies highlight circular economy opportunities in the mining industry by designing out waste and keeping products and materials in use through reuse, repurposing, repair, recycling and remanufacturing. We provide technical advice, develop strategies and formulate digital and hardware solutions.

Fabrizio Dionisio
Decarbonisation and energy transition

To support the transition from a coal-based economy to a sustainable, low-carbon and just energy future, we serve as a research and development partner to the mining sector – covering design and prototyping, testing, certification and user training. Target areas include vehicle and fleet decarbonisation and the transport value chain, specifically light delivery vehicles and heavy machinery, including the potential for dual-fuel solutions. Studies also examine hydrogen-related aspects such as infrastructure, safety and the techno-economic feasibility of production.
