The use of gravity concentration represents one of the oldest methods of mineral processing in human history and has been used as well as evolving alongside other methods as some of the earliest means of isolating rare earth minerals during the early 20th century Then it is loaded up with a mixed rare-earth acid solution that contains the complexing agent and a retaining ion such as Cu 2+ or Zn 2+ The retaining ion is needed to prevent the first rare-earth ion from spreading out and being lost during the separation process An eluant ammonium (NH 4) pushes the rare earths through the ion-exchange columnsGet price
The rare earth elements are comprised of scandium yttrium and 15 lanthanide elements of which cerium lanthanum and neodymium are the most abundant While rare earth elements are found in several minerals almost all production comes from less than 10 minerals primarily monazite and bastnasite Since the scandium industry is for theThe 17 rare earth elements or lanthanides consist of elements 21 (scandium) 39 (yttrium) and 57 (lanthanum) to 71 (lutetium) The rare earths were so named because of their low concentration in minerals which were scarce However some of the elements are not as rare as once thoughtGet price
Jun 17 2016Rare earth metals — those 17 chemically similar elements at the bottom of the periodic table — are in almost every piece of technology we use from cell phones to wind turbines to electric cars Because these elements are so similar to each other the process of separating them is time consuming expensive and dangerous Separation anxiety Mining rare earth elements is fairly straightforward if found close enough to surface they can be scooped up in open pits crushed and gravity-separated from the host minerals but separating and extracting a single REE takes a great deal of time effort and expertiseGet price
