Ionic Adsorption Clay
Ionic Clay+ 4 related classifications
Ionic adsorption clays are formed by the weathering of rare-earth-rich granite rocks in subtropical climates. The rare earth elements are adsorbed onto the surface of clay minerals. They are the world's primary source of Heavy Rare Earths (HREEs) and are mined extensively in Southern China and developing in Brazil.
Processing
DifficultyLow
Processing & Metallurgy
Simplest processing: In-situ or heap leaching with an electrolyte solution (like ammonium sulfate) desorbs the rare earths without needing to dissolve the rock. However, environmental management of the leachate is critical.
