Mining - MIT - Massachusetts Institute of Technology

    Often, a great quantity of rare earth ore is wasted due to nonideal, under researched methods of refining. Mitigating the current inefficiencies in this extensive process can lower the waste of energy, time and materials. The most common method of extracting and separating rare earth elements from mined rock is the solvent exchange method.
