Document Description
This project aims to demonstrate a cost-effective integrated process for the recovery of lithium from geothermal brines based on new high capacity selective composite sorbents comprised of inorganic lithium-ion sieves and lithium-ion-imprinted polymers; and a new sorbent regeneration process using eco-friendly carbon dioxide/ carbonic acid that will lead to direct formation of high purity lithium carbonate.

Reasons for Exemption
This project consists of a minor alteration to an existing facility through the installation of small new equipment. Specifically, a bench top ion exchange chromatograph will be installed inside of an existing facility and will be used to recover valuable metals from geothermal brines. The chromatograph will be approximately 56.1 centimeters by 22.3 centimeters by 53.3 centimeters and will weight approximately 24.5 kilograms. This project will not result in an increase in the floor area of the facility and will not expand the existing use of the facility.
