Title: Advanced Sorbent Structure Recovery of REEs, Precious Metals and Other Valuable Metals from Geothermal Waters and Its Associated Technoeconomics

Abstract

This 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 high performance for collection of trace REEs, precious and valuable metals beyond commercially available sorbents. This report details the organic and inorganic sorbent uptake, performance, and collection efficiency results for La, Eu, Ho, Ag, Cu and Zn, as well as the characterization of these select sorbent materials. The report also contains estimated costs from an in-depth techno-economic analysis of a scaled up separation process. The estimated financial payback period for installing this equipment varies between 3.3 to 5.7 years depending on the brine flow rate of the geothermal resource.

  • 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 high performance for collection of trace REEs, precious and valuable metals. The nanostructured materials typically performed better than commercially available sorbents. Data contains organic and inorganic sorbent removal efficiency, Sharkey Hot Springs (Idaho) water chemsitry analysis, and rare earth removal efficiency from select sorbents.
  • In the project ``Recovery and Utilization of Valuable Metals from Spent Fuel,`` mutual separation process of valuable metals recovered from spent fuel has been studied by using the simulated solution contained Pb, Ru, Rh, Pd and Mo. Pd was separated successfully by DHS (di-hexyl sulfide) solvent extraction method, while Pb was recovered selectively from the raffinate by neutralization precipitation of other elements. On the other hand, Rh was roughly separated by washing the precipitate with alkaline solution, so that Rh was refined by chelate resin CS-346. Outline of the mutual separation process flow sheet has been established of the combinationmore » of these techniques. The experimental results and the process flow sheet of mutual separation of valuable metals are presented in this paper.« less
  • Water form seven hydrothermal-geothermal, one geopressured-geothermal, and six Strategic Petroleum Reserve wells have been surveyed for twelve metals of special strategic and economic importance using trace chemical analysis techniques. The elements sought were Cr, Co, Mn, Ta, Sn, V, Nb, Li, Sr, Pt, Au, and Ag. Platinum was found at a concentration of ~50 ppb in a brine from the Salton Sea geothermal area. Brine from this region, as has been known from previous studies, is also rich in Li, Sr, and Mn. Higher concentrations (~900) of Sr are found in the high-salinity geopressured brines. None of the fluids containedmore » interesting concentrations of the other metals. Good recovery of precious metals at sub-ppm concentrations from synthetic high salinity brines was achieved using Amborane resin, but similar recovery in the laboratory using real brines could not be demonstrated. Several analytical techniques were compared in sensitivity for the determination of the precious metals; neutron activation analysis with carrier separation is the best for gold and platinum in geothermal brines.

  • The simultaneous recovery of uranium and copper by the sulfuric acid- ferric sulfate leaching of domesttc carbonaceous uranlum ore is found. The copper is precipitated from the sulfuric acid solution by means of iron or zinc scrap. The proposed ore flowsheet incorporates the sulfuric acid-ferric sulfate ore leaching, the cementcopper prectpitation, and separation of uranium from solution by amine extraction. The method decreases the production costs of the sodium diuranate and shows the recovery possibility of other precious metals. (auth)
  • Processing steps of the recovery of valuable metals from spent nuclear fuel are studied by means of experiments of lead extraction from high-level radioactive waste (HLW) and selective separation of noble metals from simulated waste. Lead extraction is found to be effective to recover valuable metals from the actual insoluble residue in dissolver solution of spent fuel and the calcination of high-level liquid waste. As for refining processes of noble metals extracted in lead, selective separation of ruthenium by ozone oxidation method and mutual separation of rhodium and palladium by aqueous extraction method are examined. Both methods are found tomore » have high efficiency for refining these three metals. An optimum conceptual flow sheet for recovery of valuable metals from HLW is derived from these experimental studies.« less
