Raw materials, which are of great economic importance, but for which the risk of supply bottlenecks is valid, are considered as “criticalâ€. Others, where this risk might occur due to market changes are called “potentially criticalâ€ (FFG 2012). The following metals are defined as (potentially) critical raw materials either by the EU or by the FFG: Be, Mg, Mn, Ni, Co, Zn, Cr, Al, Ga, In, rare earth elements (REE), Ge, Sb, Nb, Ta, W, V, Mo, platinum group elements (PGE).
