This is a study of the brine formulations that we were using in our testing were stable over time. The data includes charts, as well as, all of the original data from the ICP-MS runs to complete this study.
This dataset shows the ability of media #1 to be loaded with REE's, stripped of the REE's sequestered, regenerated, and reused over many cycles.
This dataset described shaker table experiments ran with sieved 50 +100 mesh media #1 in brine #1 that have 2ppm each of the 7 REE metals at different starting pH's of 3.5, 4.5, and 5.5. The experimental conditions are 2g media to 150mL of REE solution, at 70C.
Study of rare earth element (REE) uptake from geothermal brine simulant by column loading, metal recovery through stripping, and regeneration of column for re-loading. Simulated brine testing.
This data is from a regeneration study from a dynamic column extraction experiment where we ran a solution of REE's through a column of media #1 then stripped the REE's off the media using 2M HNO3 solution. We then re-equilibrated the media and repeated the process of running a RE...
This is a continuation of the rare earth element sorption study for shaker bath tests on 2g media #1 in 150mL brine #1 with different starting pH's at 70C. In a previous submission we reported data for shaker bath tests for brine #1 with starting pH's of 3.5, 4.5 and 5.5. In this ...
This dataset shows the sorption capacities of smaller grain size (-50 +100 mesh) of media #1 in brine #1 at different starting concentrations of REE's at elevated temperature of 70C. The experimental conditions are 2g of 50 +100 mesh media #1 to 150mL of REE solution at concentrat...
Shaker test data comparing rare earth element (REE) sorption onto Tusaar media between one natural geothermal brine and two simulated brines doped with known mineral concentrations.
A study exploring sorption and stripping characteristics of sorption media when simulated geothermal brines are degassed or not degassed. Experiments were done at 70degC. The brines used in this study were formulated by Tusaar. The two brines used/simulated are labeled 1M and 1C...
Presented are major element and lithium concentrations of minerals from the Salton Sea Geothermal Field (SSGF), located in the Imperial Valley, California. With a recent increase in demand for lithium, the area is now being studied as a source of geothermal brine for lithium extr...
A study comparing the REE sorption characteristics of fresh ligand-based sorption media and media partially loaded with REEs when exposed to a simulated geothermal brine with known mineral concentrations, REE7. Sorption rates were tested using microcosm shaker tests. Results sugg...
Description of a conceptual commercial process to remove rare earth elements (REEs) from geothermal brine, based on a small-scale laboratory experiment to load, strip, and regenerate a ligand-based media used to adsorb REEs from a simulated brine doped with known mineral concentra...
This data set shows the different loading capacities of Media #1 and Media #2 in a high and low salt content brine matrix at different liquid to solid ratio's. These data sets are shaker bath tests on media #1 and media #2 in brine's #1 and #2 at 500mL-.5g(1000-1 ratio), 150mL-.75...
Presented are trace element concentrations of minerals from the Salton Sea Geothermal Field (SSGF), located in the Imperial Valley, California. With a recent increase in demand for lithium, the area is actively being studied as a source of geothermal brine for lithium extraction. ...
Batch tests of cross-linked lithium and manganese imprinted polymers of variable composition to assess their ability to extract lithium and manganese from synthetic brines at T=45 deg C .
Solution chemical analysis data for magnetic core shell sorbent materials. Deionized water and brine solutions were spiked with five rare earth elements and the solutions analyzed after approximately 5 minutes exposure to the sorbent particles.
This document describes the method and results of an in-situ experiment used to confirm that ligand bleed from a sorptive media can be contained. The experiment focused on maintaining the media's sorption of rare earth elements (REE) obtained from a simulated geothermal brine dop...
Experimental results from several studies exploring the impact of pH and acid volume on the stripping of rare earth elements (REEs) loaded onto ligand-based media via an active column. The REEs in this experiment were loaded onto the media through exposure to a simulated geother...
Study on the use of organic ligands to extract lanthanides from low temperature geothermal water.
This work was developed to complement the geochemical assessments of produced water and geothermal water samples. Specifically, this task was designed to test the influence of reservoir rock-type and corresponding mineralogy/geochemistry on the concentrations of REE found in oil a...
This data describes rare earth element adsorption onto E. coli cells engineered to express a lanthanide binding tag (LBT). We used a Great Salt Lake synthetic solution as the background matrix with Tb added to 1-10,000 ppb, concentrations much lower than the competing ions presen...
These data summarize adsorption experiments conducted with Gd in 0.5 M NaCl. Results represent preliminary, proof-of-concept data utilizing fine-powder silica gel as the adsorbent support. Future testing will focus on larger, application-appropriate beads.
Results for fluid rare earth element analyses from Reykjanes wells RN-12 and RN-19. The data have not been corrected for flashing. Samples pre-concentrated using chelating resin with IDA functional group (InertSep ME-1). Analyzed using an element magnetic sector ICP-MS.
Results for laser ablation measurement of rare earth elements and electron microprobe analysis of major elements in hydrothermal epidote from the Reykjanes geothermal system in Iceland. Laser ablation measurements were completed using an Agilent 7700 quadrupole ICP-MS coupled with...
Results from a nanofiltration study utilizing simulated geothermal brines. The data includes a PDF documenting the process used to remove Calcium, Magnesium, Sodium, Silica, Lithium, Chlorine, and Sulfate from simulated geothermal brines. Three different membranes were evaluated...
