Abstract
Capillary electrophoresis is used to monitor concentration of components in streams of a lithium recovery process.
Claims20
A method of recovering lithium from a lithium source, comprising:
- withdrawing lithium from the lithium source using an ion withdrawal stage to form an eluate and a lithium-depleted stream;
- and
- monitoring concentration of one or more components in any or all of the lithium source, the eluate, and the lithium-depleted stream using a capillary electrophoresis instrument.
A method of recovering lithium from a lithium source, comprising:
- extracting lithium from the lithium source using an absorption/desorption process to form a lithium extract;
- processing the lithium extract using a concentrator to form a lithium concentrate;
- recycling a process stream from the concentrator to the absorption/desorption process;
- and
- monitoring lithium concentration in the lithium concentrate, the process stream, or both using a capillary electrophoresis instrument.
2 more elements
A method of recovering lithium from a lithium source, comprising:
- performing a plurality of sequential transformations, each transformation converting an input derived from the lithium source into an output containing lithium and a byproduct, the sequential transformations including an ion withdrawal process;
- and
- monitoring a concentration of one or more components in one or more inputs, outputs, or byproducts using one or more capillary electrophoresis instruments.
