In-Situ Process for Sorption and Stripping of Rare Earth Elements from Simulated Geothermal Brine

공공데이터포털

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 concentrations.

Experimental Parameters Affecting Stripping of Rare Earth Elements from Loaded Sorptive Media in Simulated Geothermal Brines

공공데이터포털

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 geothermal brine with known mineral concentrations. The data include the experiment results, rare earth element concentrations, and the experimental parameters varied.

Comparison of Rare Earth Element Sorption Between Fresh and Partially Loaded Media Using Simulated Geothermal Brine

공공데이터포털

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 suggest that preferential REE sorption is greater for fresh media, but this preference differs between elements.

Improved Rare Earth Element Sorption from Simulated Geothermal Brines: Effect of Gassed versus Degassed Brines

공공데이터포털

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 1CF. The data consists of a Word file explaining the results and an Excel file of the data.

Method to Recover Media Ligand Losses During Sorption of Rare Earth Elements from Simulated Geothermal Brines

공공데이터포털

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 doped with known mineral concentrations.

Rare Earth Element Sorption Study on sieved -50 +100 mesh fraction of Media 1 in Brine 1 with Different Starting pHs at 70C

공공데이터포털

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 submission we these pH's compared to starting brine #1 pH's of 6, and 7.
