Gold parting - Wikipedia

Electroparting is recent gold refining procedure where gold is separated from other metals in electrolytic cell in a way that dissolves all metals except gold and platinum. This procedure refines gold directly, producing up to 99.5% purity gold powder in a single step. AcidLess vacuum distillation process

Refining Gold by Electrolysis | Nature

THE problem presented by the necessity of refining gold was one for which a solution was sought at least as early as the time, about B.C. 700, when coins were first manufactured in the Western world.

Gold processing | 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 wavelengths less than 5600 angstroms ...

Electrolytic Refining - Mining Fundamentals

The electrolytic process is similar to gold, except that the silver anodes are dissolved in a nitric acid bath. The resulting silver will be about 99.9% pure. Copper – The extraction of copper from other ores through electrolysis involves the deposition of copper on the cathode, and using lead-coated anodes.

Reverse Electroplating for Gold Recovery | eHow

Gold is typically thought of as a metal used for coins and jewelry. However, its resistance to corrosion, conductivity and malleability makes it useful for electronics. When electronics become defective, there are ways to recover the gold, such as reverse electroplating.

Electrolytic Refining of Gold - Mineral Processing & Metallurgy

The method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution. The active agent ...
