2015-5-26 Gold refining processes 99.5% Purity and/or 99.99% Purity. Refining Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, cop- per, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process.
The Miller Process for Refining Gold Gold, Mining
2012-2-9 The process takes from 2 to 4 hours to complete with the chloride fumes being removed and filtered by a two stage wet filter or a two stage dry scrubbing system that maximizes the recovery of the chloride as well as the cleaning of the exhaust air from the process. In the process slag is poured off the top of the melt into a crucible and allowed to slowly cool so any gold that has been caught up with the chlorides will settle to the bottom where it can be recovered as a button of gold

How the Gold Refining Process Works Global Bullion
The Refining Process. Refiners start with one of two types of gold: a doré bar or scrap. Doré bars are produced by miners and are about 80 percent pure. Refiners increase the purity by separating the other precious metals and less precious metals that are mined
Extraction of Gold
Miller's dry parting process involves the action of chlorine on molten gold covered with a layer of borax to prevent spurting. The gold is not attacked, but the silver is converted into chloride. When the gold has solidified, the molten silver chloride collected on the surface is run off, carrying with it a small proportion of gold.
How Ultra-Pure Gold is Made Manhattan Gold & Silver
2017-2-7 Hans Emil Wohlwill, a German engineer, invented the Wohlwill Process in 1874. Unlike the Miller Process, which is known among refineries as a relatively cheap and easy way to produce high-purity gold (in the 99.95% purity range), the Wohlwill Process is complex and expensive.But when done correctly, it can produce gold
