Anode Choice in Gold/Nickel Recovery
Currently, I am embarking on a project to start a new recovery process of nickel and gold dragout solutions (separated). I have done some research regarding the available methods of metal recovery and is highly interested in electrowinning process due to its simplicity. However, I am not sure if the choice of anodes and/or cathodes will affect the recovery process in terms of operating cost, purity and yield of the recovered metal. What I am thinking of is use a graphite anode or platinized titanium anode with stainless steel cathode as the basic setup of the electrowinning unit. Is there also a need to combine both of the graphite anode and platinized titanium anode together to give the best result? How do you think the anodes and cathode might work in this situation? Please help.
Thank you.

The platinized titanium anode with a stainless steel cathode would be the best choice as they are used successfully in stripper cells like the "EMEW Cells". You may have to play with the power levels and anode / cathode spacing for optimum results.

Thank you for your advice Mr Jim. I would also like to ask you a question. Do you also mean that with graphite as an additional anode would be fruitless?
Thank you.

An additional graphite anode would not be needed.
Good luck,
