Electrowinning Cell and Electrolytic Cell have the same part, they are composed of Electrolytic or Electrowinning tank, rectifier power , circulation tank, circulation pump, control system, etc.
The different point: Electrolytic cells are adopted for extracting metal from coarse metal, alloy or other smelting intermediates, adopting soluble-anode (It could be used for Coarse Gold, Silver, Copper, Lead, Zinc, Tin and Nickel, etc. ), we call it electrorefining. Cathodes can be different materials according to different solution systems. By the process of electrorefining, we will get 99.999% pure metal.
But, Electrowinning or electroplating cell always used for extract the pure metal from the electrolyte. It is suitable for the metals such as copper, zinc, lead, cobalt, nickel, chromium, etc. The anodes and cathodes can be different materials according to different solution systems. In the working process, the anode plate does not dissolve. In the follow video, the anodes is titanium mesh, and the cathodes is titanium. It is suitable for different metals electrowinning. The metal ions in the electrolyte to be extracted at the cathode plates to produce pure metal. We call this process as electrowinning or electroplating.
