Abstract
There is disclosed a method and apparatus for improving lithium yield of lithium lithium-selective media in one or more packed-bed columns in a direct lithium extraction process. The method comprises the steps of a) passing the lithium-selective media and a stream of process fluid through a screening zone; and b) collecting a portion of lithium-selective media having a required particle-size distribution and/or free of contaminants.
