Raw data and data workup of assay for real-world brine sample. Brine sample was taken at the well head.
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.
This PDF outlines the experiments for determining the amount of ligand bleed from our Media #1 at various temperatures and pH's.
Description of experimental protocol used to characterize the effectiveness of regenerating ligand-based adsorption media through the addition of ligands when media were previously depleted of ligands during use. Results of the effectiveness of this regeneration are also described.
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.
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...
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...
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...
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...
This is a dataset for a 200ppm europium solution sent through a column with 12g of media #1 at pH of 3.2. This column experiment was run at ambient temperature at a flow rate of 2mL/min.
This dataset shows the capacity for Europium of media #1 and media #2 in a shakertable experiment. The experimental conditions were 150mL of 500ppm Eu solution, 2g of media, pH of 3.2, at ambient temperature.
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...
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.
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 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...
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 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...
