A newly discovered protein naturally houses an unusual binding site that can differentiate between rare earth elements, and researchers at Penn State have made it even better. Rare earth elements are key components used in everything from modern tech to gasoline production. The protein, called LanD, enriches neodymium and praseodymium over other similar rare earth elements and has the potential to revolutionize industrial mining, researchers said.

U.S. efforts to extract valuable elements from coal waste surge

Crystals of the rare earth metal polytelluride LaTe1.82(1), namely, lanthanum telluride (1/1.8), have been grown by molten alkali halide flux reactions and vapour-assisted crystallization with iodine. The two-dimensionally incommensurately modulated crystal structure has been investigated by X-ray diffraction experiments. In contrast to the tetra­gonal average structure with unit-cell dimensions of a = 4.4996 (5) and c = 9.179 (1) Å at 296 (1) K, which was solved and refined in the space group P4/nmm (No. 129), the satellite reflections are not compatible with a tetra­gonal symmetry but enforce a symmetry reduction. Possible space groups have been derived by group–subgroup relationships and by consideration of previous reports on similar rare earth metal polychalcogenide structures. Two structural models in the ortho­rhom­bic superspace group, i.e. Pmmn(α,β,1 over 2)000(−α,β,1 over 2)000 (No. 59.2.51.39) and Pm21n(α,β,1 over 2)000(−α,β,1 over 2)000 (No. 31.2.51.35), with modulation wave vectors q1 = αa* + βb* + 1 over 2c* and q2 = −αa* + βb* + 1 over 2c* [α = 0.272 (1) and β = 0.314 (1)], have been established and evaluated against each other. The modulation describes the distribution of defects in the planar [Te] layer, coupled to a displacive modulation due to the formation of different Te anions. The bonding situation in the planar [Te] layer and the different Te anion species have been investigated by density functional theory (DFT) methods and an electron localizability indicator (ELI-D)-based bonding analysis on three different approximants. The temperature-dependent electrical resistance revealed a semiconducting behaviour with an estimated band gap of 0.17 eV.

Recycling offers a promising means of supplying the rare earth elements neodymium and dysprosium, used in computing and low-carbon technologies, research suggests. If recycling infrastructure and technologies are prepared now to deal with the larger volumes of high-tech waste expected in the future, 7-9% of global demand for these critical elements could be met by recycling by the year 2030.

Rare earth elements (REEs) are used increasingly often in innovative technologies, causing these elements to enter the natural environment. They can be sourced via deep-sea mining, raising concerns about marine exposure to mining processes and waste products. This study examined how two REEs, lanthanum and yttrium, affected and stressed marine ecosystems, using young marine mussels (Mytilus galloprovincialis) as indicators of water quality. The researchers determine a parameter known as the ‘predicted no effect concentration’ (PNEC) for La and Y — the maximum environmental level of each of the two elements at which no effect is seen on the most sensitive organisms and which is, therefore, deemed safe for the environment.

There's more to salmon sperm than making salmon babies, as researchers find it can also be used to help sort out toxic waste.

A process to prepare an improved fluid rare earth phosphate catalyst composition useful in preparing alkylene oxide adducts of organic compounds having active hydrogen atoms is provided. The catalyst is prepared by dissolving a rare earth salt in a C9-C30 active hydrogen containing organic compound and then adding phosphoric acid to the organic compound rare earth mixture.

In a method for multiple cutoff machining a rare earth magnet block, a cutting fluid feed nozzle having a plurality of slits is combined with a plurality of cutoff abrasive blades coaxially mounted on a rotating shaft, each said blade comprising a base disk and a peripheral cutting part. The slits in the feed nozzle into which the outer peripheral portions of cutoff abrasive blades are inserted serve to restrict any axial run-out of the cutoff abrasive blades during rotation. Cutting fluid is fed from the feed nozzle through slits to the rotating cutoff abrasive blades and eventually to points of cutoff machining on the magnet block.

A sintered magnet body (RaT1bMcBd) coated with a powder mixture of an intermetallic compound (R1iM1j, R1xT2yM1z, R1iM1jHk), alloy (M1dM2e) or metal (M1) powder and a rare earth (R2) oxide is diffusion treated. The R2 oxide is partially reduced during the diffusion treatment, so a significant amount of R2 can be introduced near interfaces of primary phase grains within the magnet through the passages in the form of grain boundaries. The coercive force is increased while minimizing a decline of remanence.

The Browns Range pilot plant in remote Western Australia has been touted as a project that could have global significance, particularly if the US-China trade war escalates.

(Purdue University) New environmentally friendly technologies promise to be 'game changers' in the rare earth metals field and enable the US to create a more stable and reliable domestic source of these essential metals. Purdue University patented extraction and purifying processes using ligand-assisted chromatography are shown to remove and purify such metals from coal ash, recycled magnets and raw ore safely, efficiently and with virtually no detrimental environmental impact.

The rare earth metals mining industry is one rife with issues. But is there a way to green up the business?

Exports of Rare Earths in China decreased to 32800 USD THO in April from 54300 USD THO in March of 2020. Exports of Rare Earths in China averaged 34585.93 USD THO from 2014 until 2020, reaching an all time high of 54300 USD THO in March of 2020 and a record low of 19289 USD THO in February of 2014.
