Reply to comment by LummoxJR in German scientists show a commercially feasible method for cyanobacteria to extract 17 rare earth elements from low-concentration sources. Currently, most of the world's supply of these elements is mined in China. by lughnasadh

As the concentration is low. You need flow through and not batch, then need to release the water again. So you would have to change the pH on a fast flow through, capture, release, then recorrect pH for release after. There is proteins that work well at low pH for selective REE capture, LanM as an example.
