The rare earth market was flat in September, when the industry was full of pessimism about the rare earth market in October. Although it has been repeatedly stressed before that the whole rare earth industry chain is in a state of low inventory, no matter how low the inventory is, there is a long order to make up for it, which cannot cover up the mediocre performance of the bulk market, except ...

It was found that silver nanoparticles (AgNPs) could enhance co-luminescence effect of rare earths ions Tb(3+) and Y(3+). Based on this, a sensitive fluorescence detection method for the determination of dopamine (DA) was proposed. Moreover, the detection limit for DA was very low (down to nM). This …
Rare Earth (RE) elements are well known by their luminescence behavior due to their various energy levels. The 4f–4f or 5d–4f transitions are responsible for the characteristic emission from the UV to near-IR range of electromagnetic spectrum due to relaxation of excited state electrons to their ground state after absorption of light [ 1, 2 ].
According to Natural Resources Canada, Rare Earth Metals (REM) or as also referred to as Rare Earth Elements (REE), is a group of 17 elements which are used towards everyday products, such as computer memory, DVDs, batteries, cell phones and much more. Although REM is referred to as 'rare', they aren't in fact especially rare at all.

Silver may be more useful industrially, but it is somewhat less rare, so less precious. Rhodium, iridium and ruthenium are perhaps the rarest, roughly 1/5 as common as platinum. However, the sale price of rhodium is typically a bit less than that of platinum, and the rest are even less expensive because they are simply less useful.

Although silver cannot be picked up with a magnet, there is a different reaction between a powerful rare-earth magnet and pure silver as opposed to the reaction to adulterated silver. Tip the suspected bar at a 45-degree angle and place the magnet on the top end of the bar.
All stones are tested with a Smart Pro Gem-Eye I Gem Tester. This machine cannot distinguish between natural and lab created stones. Chain Length: 18". All silver is tested with a rare earth magnet.
For some elements, such as the rare earth elements (REEs), the problem is production. Current mines are not sufficient to meet demand for all the metals, particularly dysprosium and neodymium (Vaccari, 2009) (see REE demand breakdown figure below). For other elements, such as uranium, the rare metals, phosphorus and platinum group elements ...

Alexis: The hazards of rare earths come at four stages: the mining itself, refining the ore, managing the waste, and disposing of it. First, the mining. Blasting rare earths out of the earth's crust means blasting out other elements too. Elements that weren't harming anyone in the ground.

Gold, silver and platinum are that rare! More Gold Than Silver Above-ground. From the crustal abundance of precious metals, we can also see that the gold-to-silver ratio in the earth's crust is about 1:19. This means that there is roughly 19 times more silver than gold in the ground.
