What Are Critical Minerals and Metals?
Definition in the South African Context
Critical minerals and metals in South Africa are defined not solely by global supply risks but by their capacity to drive domestic economic value, support industrial development, and enable the energy transition. Unlike the European Union or United States, which emphasize supply security, South Africa's approach integrates mineral beneficiation in South Africa potential and downstream manufacturing opportunities. For example, platinum group metals (PGMs) are deemed critical not only for their export value but for their application in hydrogen fuel cells and renewable energy systems. This dual focus on economic and technological relevance ensures alignment with national priorities like job creation and industrial diversification.
Criteria for Classification
The DMPR employs a multi-criteria framework to classify minerals:
Economic Contribution: Minerals contributing over 5% to GDP or 10% to export earnings, such as coal (7.2% of 2023 exports).
Strategic Industrial Value: Resources like manganese, essential for steel production and battery alloys.
Beneficiation Potential: Chromium's use in stainless steel manufacturing exemplifies high local value addition.
Supply Chain Resilience: South Africa holds 80% of global platinum reserves, reducing dependency on external suppliers.
Green Transition Relevance: Vanadium's role in redox flow batteries for energy storage underscores its criticality.
Why South Africa Needs a Critical Minerals Strategy
Global Mineral Supply Chain Dynamics
The global demand for critical minerals for energy transition is projected to quadruple by 2040, driven by renewable energy and electric vehicle (EV) adoption. South Africa's strategy responds to geopolitical shifts, such as the EU's Critical Raw Materials Act and the U.S. Inflation Reduction Act, which incentivize localized supply chains. By securing partnerships with industrialized nations, South Africa aims to avoid the "resource curse" and transition from raw material exporter to technology supplier. For instance, PGMs account for 70% of global production, yet only 15% are currently processed domestically.
Economic Growth Opportunities
Mining contributes 8% to South Africa's GDP, but the strategy targets a 12% share by 2030 through:
Exploration Revival: A proposed 50% tax incentive for greenfield exploration projects.
Processing Expansion: The Boegoebaai manganese processing hub, set to produce 1.2 million tons annually by 2027.
Export Diversification: Shifting from raw chrome exports (95% of production) to ferrochrome, which commands triple the value.
Energy Transition Imperatives
South Africa's coal-dominated energy mix (85% of electricity) necessitates a phased transition. The strategy prioritizes PGMs for hydrogen electrolyzers and manganese for EV batteries, aligning with the Just Energy Transition Investment Plan (JET-IP). Projects like the Hydrogen Valley corridor aim to create 20,000 jobs by 2030 through PGM-driven hydrogen ecosystems.
Key Elements of South Africa's Critical Minerals Strategy
High-Critical Minerals Identification
The DMPR's classification of five high-critical minerals reflects their dominance in export earnings and industrial applications:
Platinum: 140 tons produced annually, supporting 500,000 jobs.
Manganese: 7.4 million tons mined in 2023, with 60% exported as ore.
Iron-Ore: 78 million tons produced, primarily for China's steel sector.
Coal: 250 million tons annual production, though transitioning to metallurgical uses.
Chrome Ore: 18 million tons mined, with R300 billion in untapped beneficiation potential.
Moderate to High Criticality Minerals
Gold, vanadium, and rare earth elements (REEs) are prioritized for niche applications:
Gold: 100 tons produced annually, with potential in electronics and medical tech.
Vanadium: 9,000 tons mined, critical for grid-scale energy storage.
REEs: The Steenkampskraal mine holds 80,000 tons of monazite, a key REE source.
Five Strategic Pillars
1. Enhanced Exploration
The strategy allocates R2.5 billion to modernize geological surveys, including airborne electromagnetic mapping of the Bushveld Complex. Joint ventures with firms like De Beers aim to expand exploration in underprospected regions.
2. Research and Development Focus
Mintek's R&D hub in Johannesburg will pioneer hydrometallurgical techniques for PGM recovery, targeting 95% efficiency by 2026. Collaborative projects with MIT focus on reducing rare earth processing costs by 40%.
3. Local Processing and Beneficiation
The Musina-Makhado Special Economic Zone (SEZ) will host a R45 billion stainless steel plant, processing 2 million tons of chrome annually. Tax rebates of 15% are offered for processing equipment imports.
4. Infrastructure Development
Transnet's R20 billion rail upgrade aims to reduce manganese export costs by 30% through the Northern Corridor. Eskom's dedicated 500 MW renewable energy cluster for mines will lower processing costs.
5. Strategic Partnerships
The BRICS Critical Minerals Alliance, launched in 2024, facilitates technology transfer, with China investing R15 billion in South African lithium processing facilities.
