Next, a purification process such as a Wohlwill process 22 or a Miller process 24 is used to create essentially pure gold. Both of these processes are well known to those skilled in the art. The Wohlwill process can create 99.95% pure gold, while the Miller process can create 99.5% gold purity.

Miller process – Wikipedia, the free encyclopedia. The resulting gold is 99.95% pure, but of lower purity than gold produced by the other common refining method, the Wohlwill process, which produces gold to 99.999% purity. The Miller process is commonly used for producing high-purity gold, such as in …
A process and system and for extracting and refining gold from ores using relatively benign and inexpensive chemicals, fewer process steps, and permitting the recycling and re-use of process chemicals. The invention is preferably implemented as a two part process. In a first part process, gold is extracted from the ore and dissolved in a chemical solution to form a gold complex.
Jun 17, 2011. #6. Harold, Platinum won't be eliminated very well by the Miller Process for the same reason that the gold remains pure: its chloride is not stable and will not form at that temperature, much like Pd. Rh will form a volatile trichloride at the melting point of gold.

Gold Refining. Gold mines process ore using various techniques to produce an alloy composed primarily of gold and silver, which is called a doré bar. The composition of doré can vary significantly between mines, but generally the gold doré bars The Perth Mint processes are composed of between 70-80% gold and 10-15% silver.
The only other experience I had was refining a gold complex that assayed only 1/10 of your ore. The ore was primarily quartz, with streaks of iron pyrite, silver, gold and galena. The ore was crushed fine in a ball mill, then run with cyanide and bromine. Extraction was well over 99%, even without eliminating the sulfides.
