Patent US6017428 – Electrowinning cell – Google Patents. An electrowinning cell and a cathode for use therein for removal of gold or other precious … At proper voltage, deposition of the metal starts upon the cathodes, at a rate … Therefore, there exists a need for electrowinning cathodes not requiring …
Crud and organic recovered from Electrowinning (EW) cells should under no circumstance be returned to crud processing or the SX. The extractant has most likely been oxidised and chemically altered in the EW cell, and will only serve to create issues of crud, reduced chemical capacity of the SX organic and slow phase disengagement issues.
