Environmental Review of Coal Ash as a Resource for Rare Earth and Strategic Elements

  title={Environmental Review of Coal Ash as a Resource for Rare Earth and Strategic Elements},
  author={David B Mayfield and Ari S. Lewis},
Recently, prices of strategic minerals and rare earth elements have been rising dramatically due to global supply shortages and increasing demands. These metals are integral components of advanced technologies, such as, cell-phones, wind turbines, permanent magnets, and semi-conductors.
