In gold processing: Refining. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte 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 How Ultra-Pure Gold is Made Manhattan Gold & Silver

Gold processing Refining, Smelting & Purifying Britannica
gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with Other articles where Miller process is discussed: gold processing: History: Miller’s process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill’s electrorefining process (introduced in Hamburg, Ger., in 1878), it became possible routinely to achieve higher purities than had been allowed by fire refining.Miller process ore refining Britannica

Gold processing Refining, Smelting, Purifying Britannica
Gold processing Refining, Smelting, Purifying: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in Process Of Refining Gold My Gold Guide Purifying gold using electricity is commonly known as the ‘ Wohlwill Process ’.The method got its name from Emil Wohlwill,who invented it in 1874.This requires three main components: Anode (made with Gold that needs refining),Cathode (made with 24 karat gold),and an Electrolyte solution.

Process technology development at Rand Refinery
Gold electrolysis. Around 70% of the process stock mentioned in Table 1 is held by the electro-refining operation. Stock in this area is high because the traditional Wohlwill process as applied at Rand Refinery has very large internal and external recycles. Some 50% of electrolytic production is recycled in the form of gold sludge and anode stubs.In the Wohlwill’s Electrolytic Process the anode consists of impure gold, 4 mm. thick, and the electrolyte is a solution of gold chloride, containing 25 to 30 grammes of gold per litre, and from 20 to 50 c.c. of concentrated hydrochloric acid per litre, according to the strength of the current. The liquid is heated from 60° to 70° C.Purification of Gold by Electrolysis 911 Metallurgist

Gold Dore Refining :the process, machineries and project
Gold of even greater purity (99.99%) is created by more complex and expensive electrochemical Wohlwill Process. In this, an electric current is passed through an electrolyte solution of hydrochloric acid and gold chloride. Gold of 99.5% purity is used as the anode and 99.99% pure gold plates out onto the cathode.The Wohlwill process can create 99.95% pure gold, while the Miller process can create 99.5% gold purity. The Wohlwill process is an electrolytic process wherein essentially pure gold coats a cathode, and wherein impurities such as silver form chlorides and remain near the anode. Typically, Pt and Pd also dissolve in the electrolyte.US6090341A Method and system for extracting and refining gold from

Besides its applications in the investment, jewelry, and industrial sector, gold also has a bad image.
