In copper solvent extraction, aqueousinorganic entrainment results in the carryover of unwanted species into the electrowinning process with negative cost impliions. The need to bleed is increased and the purity of the copper hode is potentially compromised, depending on the impurities being transferred (Cl, NO3, Fe, Mn).
