Abstract: An acidic group-containing solid polymer, having an acidic group such as a sulfonic acid group, a phosphoric acid group, and/or a phosphonic acid group, is dissolved in an organic solvent other than methanol. An ionic liquid is added to the solution to prepare a casting liquid. The casting liquid is subjected to casting in a cavity formed by an opening of a frame and a sheet member, each of which is composed of PTFE (fluorine-containing polymer material). Thereafter, the solvent is removed to yeild a proton conductor membrane.

Abstract: Embodiments of the invention generally provide an electrochemical plating cell having a cell body configured to contain a plating solution therein. An anode assembly is immersed in a fluid solution contained in the cell body, the anode being positioned in an anode compartment of the cell body. A cathode assembly is positioned in a cathode compartment of the cell body, and a multilevel diffusion differentiated permeable membrane is positioned between the anode compartment and the cathode compartment. The multilevel diffusion differentiated permeable membrane is generally configured to separate the anode compartment from the cathode compartment, while allowing a fluid solution to flow therethrough in a direction from the anode compartment towards the cathode compartment.

Abstract: A process for producing one or more metals from a mineral feedstock (12) is defined. The mineral is fed to a leaching apparatus (10) wherein it is contacted with electrolyte (14). The leaching apparatus has zones of decreasing oxidation potential (17, 18, 19, 20) respectively. A stream of electrolyte (14A) is removed from zone (20) and is treated to remove impurities and unwanted metals in treatment unit (25A), prior to metal recovery by electrolysis. The electrolyte after electrolysis is then returned to the leaching unit (10). A second electrolyte stream (14B) may be removed from zone (19) for recovery of additional metals. The electrolyte (14B) is treated to remove impurities and any unwanted metals in treatment unit (25B), prior to metal recovery by electrolysis. The electrolyte after electrolysis is returned to leaching unit (10). The process enables the leaching of difficult to leach minerals, including gold, and can produce one or more metals of high purity.

Abstract: In a process for the electrolytic production of magnesium by the molten salt electrolysis of magnesium chloride using a molten salt cell bath comprised mainly of one or more salts selected from alkali metal chlorides and alkaline earth metal chlorides, the molten salt bath is enriched with magnesium chloride by suspending a magnesium oxide and/or magnesium carbonate powder to form a molten suspension and passing a chlorine-containing gas through the molten suspension at a temperature of 600.degree.-900.degree. C. so as to react the suspended powder with chlorine to form magnesium chloride. The resulting molten salt enriched with magnesium chloride can be directly introduced into the cell for electrolysis, thereby eliminating moisture absorption by the highly hygroscopic magnesium chloride. A pure magnesium can be produced with a high yield and improved current efficiency.

Abstract: This invention is directed to the process and apparatus for making a polymeric membrane containing non-quaternized amine groups, with the polymer having substantially zero amounts of non-polymerized solvents. The resulting membrane is a more efficient anion membrane for recovering acid from acidic solutions by electrodialysis than the corresponding membranes containing quaternized amine groups. The membrane is made by polymerizing a monomeric mixture on a reinforcing cloth structure, which monomeric mixture is void of non-polymerizing solvents.
