Abstract: Disclosed are solutions for the recovery of elemental metals at industrial scales without smelting including, for example, the recovery of near-pure lead from recycled LABs via specialized electrolytic processing. Further disclosed are new processes, innovative electrolyzer designs, and/or novel utilization of supplemental chemicals necessary for successful electrolysis of pure metal from impure forms (e.g., pure lead from lead oxides), and especially applicable for solid-state electrolysis of mixtures comprising lead paste, electrolyte, and supplemental chemicals. With particular regard to recovering near-pure lead during LAB recycling, solid-state electrolysis of mixtures comprising impure lead (e.g., lead paste) is made possible by electrolytic processing using supplemental chemicals, and made scalable to industrial levels via utilization of a vertically-arranged series of horizontal bipolar cathodes in an electrolyzer assembly.

Abstract: An apparatus for stripping metal (12, 14) deposited on a cathode plate (16), comprises a first robotic arm (46) carrying a first stripping apparatus (40), the first stripping apparatus having a first gripping apparatus (62, 63) to grip the cathode plate such that the first robotic arm operates to lift the cathode plate out of the stripping station following stripping of the metal sheets from the cathode plate. A second robotic arm (48) carrying a second stripping apparatus (42) is located on a second side of the cathode plate, the second stripping apparatus having a second gripping apparatus (76, 77) for gripping one or both of the first sheet of metal (12) and the second sheet of metal (14). The second robotic arm can be operated to move the first sheet of metal and the second sheet of metal to a metal storage region following stripping from the cathode plate (16). The metal is stripped from the cathode plate without breaking the bridge of metal that interconnects the first sheet of metal and the second sheet of metal.

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.
