Critical Rare Earth Oxides
As rare earth prices continue to decline from their unsustainable highs in 2011, a shakeout is occurring among many rare earth junior mining companies. Those operations which were relying on high prices of for example lanthanum or cerium are now exposed. Instead mines such as Frontier’s with known metallurgical flow sheets, low opex and high proportions of critical rare earth oxides (CREOs) are likely to secure the finance needed for mine and separator construction.
Russia to stockpile rare earths
Russia’s Deputy Prime Minister Dmitry Rogozin announced that a rare earth reserve would be created in Russia, with the details to be decided. Russia has a large rare earth resource base and last year produced approximately 2,000 tonnes of rare earths, according to the USGS.
Metalysis claims new method to produce rare earth metals
Metalysis, a British firm, has produced neodymium and terbium metals from their respective oxides by solid-state electrolysis. The principle used is the same as in the production of aluminium.
Rare Earth Oxides for Waterproof Coatings
A recent study by scientists at MIT has discovered a new property of rare earth elements. Each of the lanthanides is very hydrophobic (water repellent) and retains this property at high temperatures and under abrasive conditions (i.e. when scratched). These properties are very useful in sectors such as the oil and gas industry.
