Moneyhawk, As I understand matters there are separate circuits for copper and zinc processing.
Based on the RNS of 23 Aug 2019, there are two electrowinning circuits, which I believe extracts the metal out of the concentrate. Initially only a saleable zinc concentrate is being produced so neither electrowinning circuit will be used, leaving both available for the copper production. It seems the two electrowinning circuits can be interchanged between zinc and copper metal production depending on market conditions. Back in August 2019, the plan seemed to be to use one of the electrowinning circuits for zinc metal production at the time the lead concentrate circuit came on stream in 2022. But that may well have changed so that more copper metal can be produced by using both electrowinning circuits for that metal only.
