--- Top Comments --- [Animats]: Nice. Here's MP Minerals' plant for doing that, in Alliance, TX.[1] It's a modest sized plant in an industrial park. It's fed by a huge mine in California, which has an onsite beneficiation plant. Beneficiation is the first step of separation - sorting the good stuff out from the unwanted dirt, with rock crushers, screens, and flotation. This being "rare" earth mining, the amount of good stuff is tiny relative to the unwanted dirt. This new technology works on th... [JumpCrisscross]: > Chong Liu and her colleagues knew that one of the differences between rare earth ions was the size of the water shell surrounding each one when they are dissolved in solution. Lighter rare earths like lanthanum have larger first water shell, while heavier rare earths like dysprosium have a smaller first shell. Taking advantage of that size difference, Chong Liu’s group engineered manganese oxide so that the gaps between its stacked layers were only a few water molecules wide. Then, they ... [minimaltom]: This seems very similar to the ion-exchange membrane rowow et all have been refining on youtube over the last year: https://www.youtube.com/watch?v=luulTI1RKHE&t=114s . Rowow himself has videos on using electrochemistry to extract rare elements from mining waste. [chasil]: It appears to me that the "water envelope" refers to chemical hydrates of water. So the nanostructures allow a maximum size of hydrates. How is this flushed after collection? What impels the captured molecules out of their recesses? [ycui7]: and it was created by Chinese born Professor and Student.
