Miller Process Of Refining Gold

The technology boom for developing pure gold continued with E.B. Miller’s process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill’s electro-refining process (introduced in Hamburg, Germany, in 1878). In fact, gold with purity of 99.99 percent is created using a combination of the processes.
