During electrolysis, copper II ions leave the impure copper anode and since they are positive, they are attracted to the negative cathode. Here they pick up the two electrons that are needed to form a copper metal, and this builds up pure copper. Impurities from
12/01/2019· The purification of copper by electrolysis. Copper of purity 99 includes some impurities like Fe, Zn, Ag Au, These impurities decrease the conductivity of copper for the electricity, Impure copper metal is connected to the +ve electrode anode of the battery, while a wire of fine pure copper sheets is connected to the ve electrode cathode. Both of the anode and cathode are dipped
12/07/2010· In the web site you gave above the copper that is in the impure block is dissolved in the CuSO4 solution and redeposited on the pure copper cathode.

Purification of copper When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur trapped as bubbles of sulphur dioxide in the copper hence blister copper and then cast into anodes for refining using electrolysis.
