The s-Jet ® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d 50 0.2 µm) can now be achieved with fluidized bed jet mills. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet ® System uses superheated steam as its milling gas.

Rare Earth Magnets, also known as Neodymium, NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B), may be a good option. They are strong magnets with increasing strength as the grade number increases, for example, from N35, N38 and N42.

Rare Earth Elements in Australian Heavy Mineral Sands Deposits. Rare earths-bearing minerals monazite and xenotime occur in many of Australia's heavy mineral sand deposits and, up until the mid-1990s, monazite was produced from them and exported, mainly to Europe. A brief overview of these activities is given by Hoatson et.al (2011) 138.

Stranger still is the tale of how this mine came to supply the Chinese rare earths industry. In 1952, Mountain Pass opened. First explored as a uranium deposit, it soon supplied rare earths for the electronic needs of the Cold War economy. Until the 1990s, it stood alone as the only major source of rare earths worldwide.

On July 7, Energy Fuels Inc. made its first regular shipment of a rare earth carbonate called monazite from the United States to Europe. The metal started in …

The results show that adding trace rare earth elements into carbides is effective to minish the grain size of WC/Co powder. The grain size of rare earth doped powder became two times smaller as compared with the undoped powder within ball milling times of 25–45 h. The XRD peak of Co phase disappeared after 25 h ball milling.

For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.

The amount of total rare earth elements varies from deposit to deposit, but each deposit is enriched in the heavy rare earth elements, which are far less common than the light rare earth elements. Total rare earth elements range from zero to nearly 2.2% for the waste and tailings piles and zero to nearly 4.8% for ore.

Rare Earths. The principal value of rare earths comes from Neodymium (Nd) and Praseodymium (Pr) (together "NdPr"), which are the vital elements in the manufacturing of the permanent magnets, used in turbines, motors, EVs, mobile phones – the essential building blocks for clean technology to facilitate a greener future.

The Mountain Pass Rare Earth Mine and Processing Facility is the only scaled site of its kind in the Western Hemisphere. The self-contained nature of its operations – with co-located mining, milling, separations, and finishing – creates significant cost advantages and mitigates operational risks.

Liquid-assisted grinding in a ball mill for 20 minutes gives crystalline homo- and hetero-rare-earth(iii) metal–organic frameworks by reaction between metal carbonates and benzene-1,3,5-tricarboxylic acid (H3BTC) in the presence of small amounts of DMF or water.

Rare-earth oxycarbonates Ln 2 O 2 CO 3 (Ln = rare-earth element) have been identified as materials for chemoresistive CO 2 gas sensors. Among them, previous studies identified monoclinic La 2 O 2 CO 3 as the best performing one. However, not all rare-earth elements have been investigated and, moreover, La 2 O 2 CO 3 monoclinic phase is metastable and this can influence the long term …
