Types of Gold Refining ... Miller Chlorination Process. In the Miller process, gold is refined by chlorine. Chlorine and silver combine with base metals to form chlorides, while gold is left untouched by this. Doré bars are melted in a furnace and then chlorine is added to form chlorides. After a few hours, the chlorides are removed from the ...
