, and terbium are also used in numerous electrical
hardens magnets against heat by reshaping their magnetic fields.
, which are used for making LCD panels and hybrid vehicles, the
Among a variety of rare-earth elements, neodymium and dysprosium
are widely used as a magnetic material for motors in environmentally friendly vehicles and home appliances, while erbium is used as a dopant in optical fibers and cerium as an abrasive for polishing liquid crystal display (LCD) glass.
(1) There was already ample Western concern about potential diminishing access to supplies of REEs, particularly after a 2009 draft report written by China's Ministry of Industry and Information Technology called for a total ban on foreign shipments of terbium, dysprosium
, ytterbium, thulium, and lutetium, and a restriction of neodymium, europium, cerium, and lanthanum exports.
They sound like superheroes from a Hollywood science-fiction movie: neodymium, promethium, dysprosium
As a result of a preliminary study, it was confirmed that the tailing is rich in such indispensable elements as Dy (Dysprosium
) and Nd (Neodymium), whose demand in electric vehicles and high-tech industry is expected to grow continuously in the future.
The Asian behemoth now supplies approximately 95 percent of the world's consumption of "rare earths," such as cerium, neodymium, lathanum, yttrium, and dysprosium
. Although these substances have names that look like something Dr.
Figure 8 shows neutron diffraction scans of the magnetic peaks in a film where 15 atomic planes of magnetic dysprosium
are separated by 14 atomic planes of non-magnetic yttrium, and then this basic bilayer is repeated (43,45-46).
Interesting specimens of calcite, fluorite colored by dysprosium
, chamosite, kainosite-(Y) and other minerals have been found in fresh roadcuts along New York State Route 30.
'These include Heavy REE such as dysprosium
, terbium, and yttrium, metals critically required by the US DOD, which Ucore has at a higher grade than any other NI-43-101 Compliant Resource on US soil.
It contains significant neodymium, terbium, dysprosium
and praseodymium resources (in addition to 12 other elements) and holds a net present value (NPV) of $466 million.
