Apr 10 2019nbsp018332In electrolytic refining the impure metal act as anode a strip of same pure metal as cathode soluble salt of same metal is taken as electrolytes. On electrolysis the metal at anodes get oxidised and the metal ion get reduced at cathode So that pure metal is obtained from cathode

Jan 31 2012nbsp018332I am not a chemist. That being said before internet i.e. 1990 I got about 7000 o Troy out of such tailings using NHO3. I am glad I did it under a fume hood Is there an issue with the electrolytic refining knowing that H2SO4 very dilute is used If I do the HClH2O2 it would be done outside anyway so phosphine probably will not be an
