Samples of the mid + heavy and neodymium - praseodymium products produced in May and July this year were submitted to the specialist analysts Laboratory Services International (LSI) in Rotterdam, Netherlands (part of the Intertek Group) for an independent confirmation of the purity achieved by the Peak pilot plant.
There is growing evidence of a turnaround in the rare earth sector; prices are rising for neodymium, praseodymium, dysprosium and gadolinium and are stabilising for the remaining rare earths.

Then, to stop the pulse altogether, the researchers shut off the second laser, effectively trapping the light pulse's energy and quantum identity in the praseodymium atoms' spins.
The neodymium - praseodymium oxide was produced at the Solvent Extraction Pilot Plant currently in operation at ANSTO Minerals (Australian Nuclear Science and Technology Organisation) and is the second of four separated oxide products due to be produced following the mid and heavy rare earth oxide announced on 22 May.

Discovered by Yoshi Tokura and his colleagues at the University of Tokyo, the new compounds contain copper, oxygen, the rate-earth element cerum and any one of three lanthanides: lanthanum, praseodymium or samarium.
Preliminary exploration at the site has shown rare earth mineralization with an average ore grade of approximately four percent and a relatively high percentage of heavy rare earths, such as terbium, dysprosium, europium and samarium, as well as relatively high percentages of yttrium, neodymium, and praseodymium.
Key rare earth metal products analyzed in this study include lanthanum, praseodymium, cerium, neodymium, samarium, promethium, europium, dysprosium, holmium, gadolinium, terbium, thulium, scandium, yttrium erbium, ytterbium, and lutetium.
A high purity didymium oxide (a neodymium - praseodymium mix) sample is expected in June, followed by cerium oxide and finally a lanthanum oxide.
Made with the rare earths neodymium, praseodymium and dysprosium (or terbium), NdFeB magnets are the world's most powerful permanent magnets and are key components in many advanced technologies, including high-performance motors used in the power trains of electric vehicles, hybrid vehicles and wind power generators, as well as in motors in home appliance and industrial applications.
