Can We Get Gypsum From Rare Earth

  • The behaviour of the rare earth elements during gypsum

    Dec 01, 2017· The gypsum precipitates made from mixtures of the rare earth ions had reduced contents of the heavy rare earths relative to the light rare earths. This could be advantageous as the generally more valuable heavy REEs would tend to remain dissolved for subsequent recovery.

  • Rare Earth Elements From Phosphate Waste designnews

    Rare earth elements typically are found in concentrations less than 0.1 percent in phosphate rock. That means about 100,000 tons of these elements per year end up in phosphogypsum waste—almost as much as the approximately 126,000 tons of rare earth oxides produced worldwide each year.
