    • An alkaline cell having an anode comprising zinc and a cathode comprising manganese dioxide wherein the cathode is located annularly along the inside surface of the cell housing and has a plurality of indentations on the inside of its surface facing the cell interior. Each indentation has a wall defining a channel with an opening thereto running preferably in the direction of the cell's length. The channel and opening facing the cell interior filled with anode material. The cell can have an anode current collector, typically of metal, with at least a portion of its surface extending into the cathode indentation channel. The anode current collector can have a portion of its surface extending from a point within the anode and into the cathode indentation channel through said opening. The cell can include a cathode current collector comprising a sheet of conductive material such as a sheet of metal or graphite placed within the cathode, particularly within thick regions of the cathode. The cathode current collector can be used in conjuction with a conventional single nail anode current collector or in combination with the extended surface anode current collectors of the invention. Such alkaline cells exhibit improved performance, particularly under high power application.
    • 具有包含锌的阳极和包含二氧化锰的阴极的碱性电池,其中阴极沿着电池壳体的内表面环形定位,并且在其面向电池内部的其表面的内侧具有多个压痕。 每个压痕具有限定具有开口的通道的壁,其优选沿电池长度的方向延伸。 面向电池内部的通道和开口填充有阳极材料。 电池可以具有通常为金属的阳极集电器,其表面的至少一部分延伸到阴极压痕通道。 阳极集电器可以具有其表面的一部分从阳极内的点延伸通过所述开口的阴极凹陷通道。 电池可以包括阴极集电器,其包括导电材料片,例如放置在阴极内的金属片或石墨片,特别是在阴极的厚区域内。 阴极集电器可以与传统的单指甲阳极集电器结合使用,或与本发明的扩展的表面阳极集电器组合使用。 这种碱性电池表现出改进的性能,特别是在高功率应用下。

    • A process is described for recovering non-ferrous metal values from a metal-containing sulphide material containing at least one non-ferrous metal selected from zinc, copper, lead, cobalt, nickel, silver and gold, as well as iron, comprising leaching the complex sulphide material under oxidizing conditions in a leach stage with an acidic aqueous chloride lixiviant solution containing magnesium chloride, thereby to solubilize non-ferrous metal values in the material and to leave a residue comprising iron in oxide or hydrated oxide form and also sulphur, passing resulting non-ferrous metal-containing leach liquor to a metal recovery section including a solvent extraction stage in which non-ferrous metal values are recovered by liquid-liquid extraction using a hydrophobic organic extractant phase containing a cationic transport agent for non-ferrous metal transport, recovering from the solvent extraction stage an aqueous magnesium chloride-containing raffinate, subjecting a portion of the aqueous magnesium chloride-containing raffinate from the solvent extraction stage to high temperature hydrolysis, thereby liberating hydrogen chloride and magnesium oxide, recycling another portion of the aqueous magnesium chloride containing raffinate to the leach stage, recycling liberated hydrogen chloride to the leach stage, and passing magnesium oxide formed in the high temperature hydrolysis to the solvent extraction stage for use as neutralizing agent for the cationic transport agent.
