Gold Refining Techniques Sciencing

Another large-scale gold refining technique the Wohlwill Process refines gold to 99.999 purity — the highest purity possible. Developed by Emil Wohlwill in 1987 this electrochemical process uses a 95 pure gold bar as an anode and small sheets of pure 24-karat gold The gold refining systems we offer are cutting edge and unlike anything else on the market they offer an effective alternative to commonplace refining processes like Miller Wohlwill
