EP1720916B1 Rare earth aggregate formulation

The present invention is directed to controlling aggregation of rare earth particles using block copolymers and rare earth base particles. More particularly, invention is also directed to forming stable complexes of rare earth aggregates by complexing rare earth base particles with oppositely charged-neutral di-block copolymers. Even more particularly, invention is also directed to forming

Aggregate Evolution Mechanism during Ion

2.2. Chemical Replacement. Rare earth elements are found in strong weathered granites in the form of ions. An NH 4 Cl solution is typically used during the leaching process [22, 23].The rare earth cations adsorbed onto the ore body are replaced by NH 4 +, which has relatively active chemical properties, as shown in Formula .This strong chemical reaction occurs throughout the leaching process.

Rare Earth Recycling Department of Energy

2021-2-25  By developing a new organic compound (H 3 TriNOx) for binding rare earth cations, this group formed 15 different rare earth compounds. Solution studies revealed that the "early" rare earth compounds (containing lanthanum, cerium, praseodymium, neodymium, samarium, or europium) preferred to aggregate and form dimeric species.

Rare Earths Archives MiningFeeds

2021-2-18  Rare earth elements (or rare earth metals) are a set of seventeen chemical elements in the periodic table, namely the fifteen lanthanides plus scandium and yttrium. Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and have similar chemical properties.
