Document Description
The project has several objectives: 1) to develop and validate improved lithium extraction technologies; 2) to develop processes to transform the extracted materials into saleable products, and 3) to develop technology for cost-effective extraction of additional materials (manganese, zinc, boron, potassium, cesium and rubidium) from U.S. geothermal brines of varying salinity. To accomplish this, the project must first demonstrate a technique for managing silica and reducing scaling in equipment and piping, and Simbol must acquire and confirm an agreement with a geothermal generator for a field scale demonstration. As Simbol points out, the brines of the Salton Sea in CA, a major geothermal resource area, are particularly rich in the minerals of interest. It would be a significant benefit to CA if successful extraction processes could be developed and demonstrated in the Salton Sea area. Other geothermal fields in CA do not have the same hypersaline chemistry that the Salton Sea does, making this area the prime choice for such a demonstration. Cal Energy has confirmed to staff that they have an access agreement with Simbol for the field scale pilot demonstration plant to be constructed at Cal Energy's Elmore field.
