| 20100261034 | COMPOSITE METALLIC MATERIALS, USES THEREOF AND PROCESS FOR MAKING SAME - A lightweight, high strength and corrosion resistant composite metallic material is disclosed herein. The composite metallic material typically comprises a high-to-weight ratio, low density core material; and a corrosion resistant protective refractory metal layer. The method for making the composite metallic material comprises the steps of surface activating the core material and forming a refractory metal on the surface of the surface activated core material by physical, chemical or electrochemical processes. Such a composite material is suitable for making biomaterials, corrosion resistant equipment and industrial electrodes. | 10-14-2010 |
| 20110089045 | ELECTROCHEMICAL PROCESS FOR THE RECOVERY OF METALLIC IRON AND SULFURIC ACID VALUES FROM IRON-RICH SULFATE WASTES, MINING RESIDUES AND PICKLING LIQUORS - An electrochemical process for the recovery of metallic iron or an iron-rich alloy, oxygen and sulfuric acid from iron-rich metal sulfate wastes is described. Broadly, the electrochemical process comprises providing an iron-rich metal sulfate solution; electrolyzing the iron-rich metal sulfate solution in an electrolyzer comprising a cathodic compartment equipped with a cathode having a hydrogen over-potential equal or higher than that of iron and containing a catholyte having a pH below about 6.0; an anodic compartment equipped with an anode and containing an anolyte; and a separator allowing for anion passage; and recovering electrodeposited iron or iron-rich alloy, sulfuric acid and oxygen gas. Electrolyzing the iron-rich metal sulfate solution causes iron or an iron-rich alloy to be electrodeposited at the cathode, nascent oxygen gas to evolve at the anode, sulfuric acid to accumulate in the anodic compartment and an iron depleted solution to be produced. | 04-21-2011 |

| 20100044243 | ELECTROCHEMICAL PROCESS FOR THE RECOVERY OF METALLIC IRON AND CHLORINE VALUES FROM IRON-RICH METAL CHLORIDE WASTES - An electrochemical process for the concurrent recovery of iron metal and chlorine gas from an iron-rich metal chloride solution, comprising electrolysing the iron-rich metal chloride solution in an electrolyser comprising a cathodic compartment equipped with a cathode having a hydrogen overpotential higher than that of iron and containing a catholyte having a pH below about 2, an anodic compartment equipped with an anode and containing an anolyte, and a separator allowing for anion passage, the electrolysing step comprising circulating the iron-rich metal chloride solution in a non-anodic compartment of the electrolyser, thereby causing iron to be electrodeposited at the cathode and chlorine gas to evolve at the anode, and leaving an iron-depleted solution. The iron-rich metal chloride solution may originate from carbo-chlorination wastes, spent acid leaching liquors or pickling liquors. | 02-25-2010 |

The iron-rich metal chloride solution may originate from carbo-chlorination wastes, spent acid leaching liquors or pickling liquors. | 05-19-2011 |
