Can u explain the full process
Oh Yes Sir , Concentration- Froth-floatation process,, Treatment with NaCN--Ag2S+4NaCN-----> 2Na{Ag(CN)2} +Na2S ,,,,, Precipitation of silver-2Na{Ag(CN)2}+ZN-----> Na2{Zn(CN)4}+2Ag. \|/,,Electrolytic Refining--Pur silver in cathode ,,, Impure silver in Anode ,,,,, This the Last Answer
----> means irreversible reactions

The pure metal from the anode will dissolve in the electrolyte bath and then collect at the anode. The impurities will either dissolve or be found in a heap at the base of the anode. Copper refining is done by the electrolytic process. Its impurities of iron and zinc will dissolve in the copper sulphate solution.
