What Is the Miller Process? wiseGEEK

The Miller process is a gold refining process that produces gold of approximately 99.95% purity, sufficient for many applications. It is faster and less costly than other refining options used to produce purer gold, which makes it a popular choice at some refineries.

2021-9-29  Gold mines process ore using various techniques to produce an alloy composed mostly of gold and silver, which is called a Dore bar. Many Gold Dore bars are composed of approximately 70-80 gold and 10-15 silver. The Dore bars go through a refining process, also known as the Miller and Wohlwill process which produces gold to a purity of 99.9.
