Raw Material Criticality in the Context of Classical Risk Assessment

摘要: Abstract The rapid economic development of emerging countries in combination with an accelerating spread new technologies has led to a strongly increasing demand for industrial metals and minerals regarding both the total material requirement diversity elements used production specific high-tech applications. Several minor metal markets which are often characterized by high market concentrations raw at country company level have shown turbulences since beginning 21st century. This growing concerns about security supply, particularly established western economies. As result, numerous studies on supply risks criticality different regions were carried out recently. In this paper, we discuss methodology assessment within matrix is modification classical risk matrix. Therefore, first provide overview approaches results major quantifying means By applying uniform scaling matrices recent studies, direct comparison data interpretation was enabled. close relation between analysis overlooked most may lead misunderstanding misinterpretation results. We posit that coordinates thresholds separating critical non-critical materials need be revised general definitions.
