A criticality assessment framework is introduced to quantitatively evaluate mineral supply-risk drivers, end-user vulnerabilities, market-dynamic indicators, and their interconnections in a time-dependent manner. Using this framework, we analyzed the criticality of platinum from 1975 to 2015, considering major regional end users (Europe, North America, Japan, and China) and producers (South Africa and Russia). Our analysis demonstrates that: (1) The global supply risk of platinum is strongly influenced by South Africa's socio-political status and its dominance over global supply and reserves; (2) Production from South Africa is directly affected by the level of social progress in the region,..
