08-07-2015· Miller Gold Refining Process by Chlorination. It has been noted that the slag may content 1-2% of gold as small beads and tiny particles of gold produced by the reaction of chlorine gas and the molten charge. Usually, the gold is recovered by adding sodium carbonate to the molten charge.
the miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.95%). it was invented by francis bowyer miller ( patented 1867). this chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten but impure gold. this process purifies the gold because nearly all other elements will form chlorides
