This makes the acid and the base the main consumables in the solvent extraction process, and the spent REE acidic solution becomes one of the main pollution sources. Using this method, a plant producing multiple single rare earth products may contain hundreds and sometimes over a thousand of mixers and settlers.
New extraction processes/technologies were patented. Apparently, however, the softening price for REEs meant that it was not economical to scale up the Nippon-JBI operation beyond the experimental plant. That, at least, is the assumption. Further, it is not this newspaper's sense that much has happened with the project over the past five years.
