The components are pressed or extruded to make more complex shapes and magnetization powders than are typically available in sintered magnets. The company states they have "unique and proprietary RE recovery/processing technology.". A July 2017 Edison broker report with a valuation of AUD 0.71 can be read here. It has often been said - "Rare Earths are the "vitamins" required for the shift from a carbon based economy to the new 21st century electron economy." These 15 elements, plus scandium and yttrium, are termed "rare earth elements" (REEs). Not only do rare earths create radioactive waste residue, but according to the Chinese Society for Rare Earths, one ton of calcined rare earth ore generates 9,600 to 12,000 cubic meters(339,021 to 423,776 cubic feet) of waste gas containing dust concentrate, hydrofluoric acid, sulfur dioxide, and sulfuric acid, [and] approximately 75 cubic meters (2,649 cubic feet) of acidic wastewater.. Northern Minerals [ASX:NTU] - Price AUD 0.12. Neodymium magnets are not a controlled substance unless used in a manner that violates Federal Law. By contrast, induction motors (which are much more common) use no magnets and rely on current flowing through the stator windings to induce a magnetic field, which leads to the rotation of the rotor. Theyre so strong that they have replaced other types of magnets in many applications. This technology is currently being experimented with for applications from hoverboards to efficient vehicles, as well and moving industrial parts. This has been an avenue of research for some time: the 2015 Sustainable Materials and Technologies paper noted that finding a way to reliably reduce the grain size of components of rare earth magnets could increase the magnetic energy stored in a magnet.
