摘要： This invention relates to an apparatus for producing a metal powder product using either conventional electrowinning or alternative anode reaction chemistries in a flow-through electrowinning cell. A new design for a flow-through electrowinning cell that employs both flow-through anodes and flow-through cathodes is described. The present invention enables the production of high quality metal powders, including copper powder, from metal-containing solutions using conventional electrowinning processes, direct electrowinning, or alternative anode reaction chemistry.

摘要： The present invention relates, generally, to a method for electrowinning copper powder, and more particularly to a method for electrowinning copper powder from a copper-containing solution using the ferrous/ferric anode reaction. In accordance with various embodiments of the present invention, a process for producing copper powder by electrowinning employs alternative anode reaction technology, namely, the ferrous/ferric anode reaction, and enables the efficient and cost-effective production of copper powder at a total cell voltage of less than about 1.5 V and at current densities of greater than 50 A/ft2. A copper powder electrowinning process in accordance with the present invention also reduces or eliminates acid mist generation that is characteristic of electrowinning operations utilizing conventional electrowinning chemistry (e.g., oxygen evolution at the anode), which is advantageous.
摘要翻译：本发明一般涉及一种电解冶金铜粉的方法，更具体地涉及一种使用亚铁/三价铁阳极反应从含铜溶液中电解提取铜粉的方法。根据本发明的各种实施方案，通过电解冶金制备铜粉的方法采用替代性阳极反应技术，即亚铁/三价铁阳极反应，并且能够以总电池电压有效和成本有效地生产铜粉小于约1.5V且电流密度大于50A / ft 2。根据本发明的铜粉电解提取方法还减少或消除了利用常规电解冶金化学（例如阳极氧气析出）的电解提取操作的特征的酸雾产生，这是有利的。

摘要： The present invention relates, generally, to a method and apparatus for electrowinning metals, and more particularly to a method and apparatus for copper electrowinning using the ferrous/ferric anode reaction and a flow-through anode, such as, for example, a dimensionally stable carbon, carbon composite, metal-graphite, or stainless steel anode. In general, the use of a flow-through anode—coupled with an effective electrolyte circulation system—enables the efficient and cost-effective operation of a copper electrowinning system employing the ferrous/ferric anode reaction at a total cell voltage of less than about 1.5 V and at current densities of greater than about 26 Amps per square foot (about 280 A/m2), and reduces acid mist generation. Furthermore, the use of such a system permits the use of low ferrous iron concentrations and optimized electrolyte flow rates as compared to prior art systems while producing high quality, commercially saleable product (i.e., LME Grade A copper cathode or equivalent), which is advantageous.
