Separation of Rare Earth Elements American stone

The very first stone published by James in the Journal of the American stone Society, "A New Method for the Separation of the Yttrium Earths," indicates the direction of his research. Keenly motivated to improve the methods of separation and endowed with imagination and determination, James experimented with the preparation of many different salts of the rare earths

How to Separate Heavy Rare Earth Elements

Twelve pairs of adjacent rare earths were saturated on separate 100-g lots of H form iminodiacetic resin and six pairs of adjacent rare earths were saturated on separate 10-g lots of sulfonic resin. Sulfonic resin loads approximately 10 times as much REE as does iminodiacetic resin; therefore, the different lot sizes for the two resins were selected to keep equivalent total

Processing a rare earth mineral deposit using gravity and

Rare earth (RE) mineral deposits are typically processed using several different unit operations including flotation, gravity, magnetic and electrostatic separation techniques. Two of the most important beneficiation techniques for RE minerals are gravity and magnetic separation. Many RE minerals are found alongside low specific gravity gangue minerals thereby permitting the use of gravity

The DMS process involves the mixing of a pre-prepared ore stream with a dense medium of selected specific gravity (SG) in a mixing box and passing this mixture through a dense medium cyclone (DM cyclone). It is here that separation of the high and low SG fractions of the ore occurs. Prominer’s DMS modular plants are available with throughput capacities 8, 20, 50, 100 & 150 tons/hour. It is
