The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). [1] 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.
Gold, unlike money, is a finite valuable material which can be used as a hedge against the inflation cause by increasing the money supply. [134] Gold has this inverse relationship with the US dollar which is used as a reserve asset by many central banks thus protecting the central banks reserves when there is a dip in the US dollar or the money ...

Year to date, the VanEck Gold Miners ETF , composed of companies involved in discovering, mining, and refining gold or silver, is up 33% versus gold's 29% rise during the same period. Miners have ...
The resulting gold is 99.5% pure, but of lower purity than gold produced by the other common refining method, the Wohlwill process, which produces gold of up to 99.999% purity. [1] [2] The Wohlwill process is commonly used for producing high-purity gold, such as in electronics work, where exacting standards of purity are required.
Gold shined in 2024, outperforming many other investment assets this year. Gold's trajectory can be traced back to late 2023, when its price surged to a record high of $2,135.39 per ounce due to ...
The great expense of refining the metal made the small available quantity of pure aluminium more valuable than gold. [16] Bars of aluminium were exhibited at the Exposition Universelle of 1855 , [ 17 ] and Napoleon III 's most important guests were given aluminium cutlery, while those less worthy dined with mere silver.
