摘要： A method and apparatus for maintaining electro-deposition of metal on a cathode in an electrolytic cell. The cell comprises a metal anode, a cathode, an electrolytic bath and a main power supply to apply an electric potential across the anode and cathode resulting in a forward current and depostion of metal from said anode to the cathode. An auxiliary power supply is also provided for connection to the cell. In cases where the mains power supply falls below a predetermined value, the auxiliary power supply maintains a predetermined direction and quantity of current flow in the cell. The auxiliary power supply may be continuous or activated only when the current flow and/or direction of current falls below said predetermined value.

摘要： An arrangement and method are provided for the safe removal of a wet, fully-plated cathode (8) from a silver recovery cell (2) and its replacement by a fresh cathode. The fresh cathode is brought to the recovery cell in a transport housing (20), which is then docked thereto. A drip tray (30) is unfolded from the transport housing so as to extend across and surround the top of the recovery cell. The fresh cathode is removed from the transport housing and put to one side. The used cathode is removed from the recovery cell, preferably by being attached to the lid which is unscrewed therefrom. The cathode is then transferred to the housing over the drip tray which catches any liquid falling therefrom. The used cathode is screwed into the transport housing, and the housing removed to a refiner for safe disposal, whilst the fresh electrode is screwed onto the recovery cell.

摘要： Recovery of silver from a photographic fixer solution in an electrolytic cell is controlled so as to maintain a high current efficiency whilst minimising unwanted side effects.
The difference between plating voltages when operating at two different current levels is monitored, and the plating current adjusted in response to detection of a maximum of said differences.
Such control allows the cell to be operated continually at high current efficiency in response to changing chemical conditions within the cell.摘要翻译： 控制从电解池中的照相定影剂溶液中回收银，以便保持高电流效率同时最小化不希望的副作用。 监测在两个不同电流水平下工作时的电镀电压之间的差异，并且响应于检测到所述差异的最大值来调整电镀电流。 这种控制允许电池响应于电池内的变化的化学条件以高电流效率连续地操作。

摘要： This invention relates to a process for making shaped copper articles directly from a copper-bearing material wherein a copper bearing material (10) is contacted with an effective amount of an aqueous leaching solution (40) to form a copper-rich aqueous solution which is contacted with a water-insoluble extractant in which copper ions are transferred from the former to the latter (20, 18) forming a copper-rich extractant (51) and a copper-depleated aqueous solution (73) which are separated followed by contacting the copper-rich extractant with an aqueous stripping solution (60) transferring the copper ions from the former to the latter thereby creating a copper-rich aqueous stripping solution which is piped to an electrowinning cell (124) wherein the copper ions contained in the solution are deposited as copper powder on the cathodes (126), followed by the removal of the copper powder from the cathode (129), followed by extruding, forging, or molding the copper powder (154) to produce a shaped copper article.
