The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). The process was invented in 1874 by Emil Wohlwill.This electrochemical process involves using a cast gold ingot, often called a Doré bar, of 95%+ gold to serve as an anode.Lower percentages of gold in the anode will interfere with the reaction, especially when the ...

Refining gold is simply the process of removing the finer impurities that the smelting process could not remove. There are several methods used to refine gold. The most common gold refining methods include: 1. Miller Process . This is a chlorination process that refines gold to a purity of about 99.5%.

Inquartation and Parting. The technique mirrors part of the Fire Assay process used in the analysis (assay) of gold. Inquartation involves initially diluting the gold in the refinable material to about 25% (literally ‘quartering’ the gold) by melting with the appropriate addition of copper or silver, granulating the melt so as to generate a high surface area and then treating with nitric acid.
