anodes and cathodes electrowining gold

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.

Electrowinning and Smelting - Resource Book

Electrowinning is performed in cells, constructed of non-conducting plastic material. The cell contains a set of cathodes (negative electrodes) and anodes (positive electrodes) immersed in the gold bearing eluate delivered from the elution circuit, or Sunrise Reactor. The eluate acts as a conductor between the cathodes and anodes.

How to Define Anode and Cathode - ThoughtCo

21/11/2019  The cathode is the source of electrons or an electron donor. It may accept positive charge. Because the cathode may generate electrons, which typically are the electrical species doing the actual movement, it may be said that cathodes generate charge or that current moves from the cathode to the anode.
