Silver-Silver Sulfide Reference Electrode
This invention is a new reference electrode that was prepared by anodizing (electrochemically oxidizing) silver metal in a sodium sulfide solution (SSSE). This results in a silver metal wire coated with silver sulfide. The electrode is extremely stable. The measured potentials for SSSE versus SSCE during two experiments in 1 molar KCl in air were 0.883...

A System, Apparatus, And Process For Leaching Metal And Storing Thermal Energy During Metal Extraction
Researchers at the University of Arizona have developed a new single vessel or “one pot” copper electrorefinery process that utilizes a molten chloride salt (NaCl – KCl – ZnCl2) as both the extracting fluid and electrolyte.
Background:
Several European and South American cities have regulated or banned traditional precious...

Optimized Ore Processing using Molten Salts for Leaching and Thermal Energy Storage
University of Arizona researchers have developed and optimized an electrochemical metal extraction process utilizing molten chloride salt. The salt serves as a heat transfer fluid, which can power the process itself or provide power to outside processing units or communities. The material, or slag, leftover from the process is non-toxic and may easily...

Molten Salts for Precious Metal Recovery
This invention is a method used primarily for mining that extracts metals using electrodeposition from a mixture of refined ore and molten salt in order to reduce the melting point. Much like the process of extracting aluminum from Bauxite, gold is extracted from ore using electrodeposition as a replacement for the widely used sodium cyanide mixture.
Background:...
