How Does South Africa Define Critical Minerals?
South Africa defines critical minerals as "minerals that are essential for the overall economic development, job creation, industrial advancement and contribution to national security." This definition reflects the country's focus on using its mineral resources to drive inclusive growth and economic transformation.
The classification of critical minerals in South Africa follows a rigorous methodology based on five primary criteria:
- Export significance
- Local economic significance
- Industrial importance
- Development alignment
- Global market demand
These criteria are evaluated using eight distinct indicators including supply risk, export potential, employment impact, domestic and export sales, substitutability, and importation requirements for locally unavailable resources. Each mineral receives a score from 1-10 across all five criteria, allowing for objective classification.
"Critical minerals are 'minerals essential for economic development, job creation, industrial advancement, and national security.'" — South African Critical Minerals Strategy
This comprehensive approach ensures the criticality assessment captures both domestic priorities and global market dynamics. For example, platinum group metals score highly due to their export revenue significance and industrial applications, while also contributing approximately 40% of mining employment in South Africa.
Important technical detail: The South African model differs from approaches used by the EU and United States by explicitly incorporating domestic development priorities rather than focusing solely on supply risk and economic importance. This reflects South Africa's dual role as both a major producer and an industrializing economy seeking to capture more value from its mineral resources.
