Abstract
This invention relates to a method for producing geothermal power using geothermal brines while producing a reduced silica and iron brine having improved injectivity. The resulting compositions include a composition with reduced silica, iron, and lithium having reduced quantity of total suspended solids.
Claims10
A process for recovering lithium from a brine, the process comprising:
- providing a treated brine comprising lithium to a column for capturing lithium from the treated brine, wherein the treated brine composition has a pH of about 4.0 to about 6.0 that has less than about 20 ppm by weight of silica, less than about 20 ppm by weight of iron;
- contacting the treated brine with an extraction material in the column to selectively capture lithium to produce a lithium complex;
- passing water through the column to produce a lithium-rich stream comprising the lithium complex, wherein the lithium-rich stream comprises a higher concentration of lithium than the treated brine;
- and
- recovering lithium from the lithium-rich stream.
