Zinc and silver recoveries from zinc–lead–iron complex

2003-4-1  The pregnant solution can be sent to the electrowinning circuit for the zinc recovery (either directly or by SX/EW of zinc) and the residue can be leached using cyanide for silver extraction. In the temperature range of 110–150 °C, elemental sulphur is the main product of the oxidation and the sulphur can be floated for sales or discarded.get price
