Can I recover copper from this? Copper recovery from the

A good example is electrowinning copper in the presence of high concentrations of zinc. Copper is much more noble than zinc, hence it can easily be electrowon (under the right conditions) from zinc even if the latter is 10x more concentrated without any impact on the purity of the copper cathode produced. Silver can similarly be electrowon from
