This GDR submission is an interim technical report and raw data files from the first year of testing on functionalized nanoparticles for rare earth element extraction from geothermal fluids. The report contains Rare Earth Element uptake results (percent removal, mg Rare Earth Ele...
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.
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...
Version 2. This study is a joint effort by the University of Wyoming (UW), the UW Engineering Department (UW-ENG), and Idaho National Laboratories (INL) and the United States Geological Survey (USGS) to describe rare earth element concentrations in oil and gas produced waters. In ...
This study is a joint effort by the University of Wyoming (UW), the UW Engineering Department (UW-ENG), and Idaho National Laboratories (INL) and the United States Geological Survey (USGS) to describe rare earth element concentrations in oil and gas produced waters. In this work w...
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...
The work evaluates, develops and demonstrates flexible, scalable mineral extraction technology for geothermal brines based upon solid phase sorbent materials with a specific focus upon rare earth elements (REEs). The selected organic and inorganic sorbent materials demonstrated h...
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 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...
This study is part of a joint effort by the University of Wyoming (UW) School of Energy Resources (SER), the UW Engineering Department, Idaho National Laboratories (INL), and the United States Geological Survey (USGS) to describe rare earth element concentrations in oil and gas pr...
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.
The current uncertainty in the global supply of rare earth elements (REEs) necessitates the development of novel extraction technologies that utilize a variety of REE source materials. Herein, we examined the techno-economic performance of integrating a biosorption approach into a...
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.
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...
Lanthanide binding tags (LBTs) have been engineered onto native Escherichia coli (E. coli) bacterial surfaces to enhance extraction and recovery of rare earth elements (REEs). Three strains of E. coli were studied: (1) the native E. coli surface, (2) a mutant E. coli surface with ...
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.
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...
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 submission includes data collected from experiments on the performance of rare earth adsorption by immobilized bacteria that accompany the FY18 Q2 and Q3 quarter reports. Relevant information from these reports is included in a resource below. The spreadsheet below includes d...
Raw data and data workup of assay for real-world brine sample. Brine sample was taken at the well head.
We summarized the FY17 and part of FY18 results of the analysis of the effect of several parameters (e.g., total dissolved solids, specific competing metals, pH, and temperature) on REE recovery from geothermal brine in a manuscript that was submitted to Environmental Science & Te...
The work evaluates, develops and demonstrates flexible, scalable mineral extraction technology for geothermal brines based upon solid phase sorbent materials with a specific focus upon rare earth elements (REEs). The selected organic and inorganic sorbent materials (silica and MOF...
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 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.
