Concentration and Separation of Rare Earths from Bastnasite

Generally, a 60 to 70 percent rare-earth concentrate is prepared from bastnasite ore by crushing and grinding the ore to minus 100 mesh, followed by froth flotation. The resulting concentrate is the feed material for further acid leaching and separation operations. A variety of techniques are available for processing the concentrates.Rare Earth Elements Purification, Separation and RecyclingLREE Light Rare Earth Element/s, also known as the cerium group (Sc, La, Ce, Pr, Nd, Pm, Sm, Eu, and Gd) HREE Heavy Rare Earth Element/s, also known as the yttrium group (Y, Tb, Dy, Ho, Er, Tm, Yb, and Lu) MREE Middle Rare Earth Elements.
