Abstract: A device and method for preparing high-purity titanium powder by continuous electrolysis are provided. The method includes: electrolyzing a titanium-containing conductive ceramic anode and a rotatable cathode in a fused salt electrolytic tank; continuously transferring titanium powder deposited on a surface of the cathode by the rotatable cathode to a position above the fused salt; scraping the titanium powder by a discharging scraper, and collecting; filtering the titanium powder, and recovering the fused salt; cooling separated titanium powder, washing with deoxygenated and deionized water, and vacuum-drying to obtain final titanium powder. The device includes a fused salt electrolysis mechanism, a continuous titanium powder collection mechanism, a filtering mechanism, a washing mechanism, and a vacuum-drying mechanism.

Abstract: The present invention concerns a process for the recovery of lead from a lead pastel electrolytically, where the pastel contains lead sulfate. The process provides for the leaching of the non-desulfurised pastel and the subsequent removal of the sulfates by precipitation; the leachate containing the lead ions is then subjected to electrolysis for the recovery of metal lead. The present invention further relates to a process for the recovery of lead accumulator components, wherein the lead contained in the pastel of the accumulators is recovered according to the aforesaid process.

Abstract: Lead from lead acid battery scrap is recovered in two separate production streams as clean grid lead and as high-purity lead without smelting. In preferred aspects, lead recovery is performed in a continuous process that uses an aqueous electroprocessing solvent and electro-refining, and spent electroprocessing solvent can be recycled to the recovery process.

Abstract: A system to remove sodium and Sulfur from a feed stream containing alkali metal sulfides and polysulfides in addition to heavy metals. The system includes an electrolytic cell having an anolyte compartment housing an anode in contact with an anolyte. The anolyte includes alkali metal sulfides and polysulfides dissolved in a polar organic solvent. The anolyte includes heavy metal ions. A separator includes an ion conducting membrane and separates the anolyte compartment from a catholyte compartment that includes a cathode in contact with a catholyte. The catholyte includes an alkali ion-conductive liquid. A power source applies a voltage to the electrolytic cell high enough to reduce the alkali metal and oxidize Sulfur ions to allow recovery of the alkali metal and elemental sulfur. The ratio of sodium to Sulfur is such that the open circuit potential of the electrolytic cell is greater than about 2.3V.

Abstract: Provided is a copper powder in which the number of contact points between copper powder particles is increased to allow excellent electric conductivity to be achieved, and which can be used suitably in use applications including an electrically conductive paste and an electromagnetic wave shield. The copper powder according to the present invention has a dendritic shape composed of a main stem that is grown linearly and multiple branches that are branched from the main stem, wherein the main stem and the branches are composed of a flat-plate-like cupper particle having a cross section with an average thickness of 0.2 to 1.0 μm, and the average particle diameter (D50) of the copper powder is 5.0 to 30 μm. A copper paste having excellent electric conductivity can be produced by mixing the dendritic copper powder with a resin.

Abstract: This relates to mining and mineral or materials treatment industries that deal with gold and silver. Specifically, it is related to the process to recover gold and silver from thiosulfate or thiourea solutions, with an electrolysis that occurs simultaneously on both the anode and cathode. Increased velocity and greatly reduced energy consumption are obtained in relation to those found in conventional electrolytic cells.
