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.
Claims15
A method for processing lithium-selective media in one or more packed-bed columns in a direct lithium extraction process, the method comprising the steps of:
- a) unloading the lithium-selective media from one or more packed-bed columns;
- b) passing the lithium-selective media and a stream of process fluid through a screening zone, wherein the screening zone comprises a first sieve element having a first mesh size of approximately 1.5 mm to 2.5 mm;
- and
- c) collecting a first portion of the lithium-selective media having a particle-size no greater than the first mesh size, wherein the first portion of the lithium-selective media is separated from a second portion of the lithium-selective media having a particle-size larger than the first mesh size.
