Rare Earths Mining Processing Equipment Flow Chart

Rare Earths Mining. Rare earths are a set of 17 chemical elements in the periodic table that, because of their unique geochemical properties, are typically widely dispersed in the Earth’s crust and are not often found in concentrated and economically exploitable forms. This fact requires special recovery and refining techniques to produce
