  • Electrowinning an overview | ScienceDirect Topics

    An electrowinning cell of novel design has been described by Treasure (2000).Named as EMEW R cell, it consists of a cylindrical in place of planar electrodes. The outer tube is the cathode and the inner one is anode. The diameters of the electrode tubes are sized according to the particular application to minimize cell voltage for a given solution chemistry.

  • Electrowinning an overview | ScienceDirect Topics

    Electrowinning is the process of “winning” metal from solution using an applied voltage. Gold electrowinning is usually performed in relatively small vessels or cells that are about 1 m long and contain less than 1 m 3 of solution. These cells often contain several cathodes and anodes, although there is one extra anode. The cathodes commonly consist of steel wool (30 kg m − 3)

  • Electrowinning and Smelting Resource Book

    Electrowinning Theory Gold is recovered from pregnant (gold bearing) solution by the process of electrowinning. An electric current is passed through the solution causing solid gold to plate out on steel wool cathodes. Electrowinning is performed in cells, constructed of non-conducting plastic material. The cell contains a set of cathodes (negative electrodes) and anodes (positive
