World Resources Resources of scandium are abundant. Scandiums crustal abundance is greater than that of lead. Scandium lacks affinity for the common ore-forming anions therefore, it is widely dispersed in the lithosphere and forms solid solutions with low concentrations in more than 100 minerals. Scandium resources have been identified in
