Opening New Mines

The technology to mine and refine REEs from bedrock deposits only became available in the 1960s. Before then, only placer deposits, which are created from density sorting by water currents, were used for mining REEs. (Leifert, 2010) The denser materials tend to accumulate in one place because it takes more energy to move the dense minerals.
