  • Galvanic and Corrosion Compatibility Dissimilar Metal

    Quality engineering and design requires an understanding of material compatibility. Galvanic corrosion (some times called dissimilar metal corrosion) is the process by which the materials in contact with each other oxidizes or corrodes. There are three conditions that must exist for galvanic corrosion to occur.

  • Gold parting

    Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to

  • Electroplating

    [clarification needed] Electroless nickel plating uses hypophosphite as the reducer while plating of other metals like silver, gold and copper, typically use low molecular weight aldehydes. A major benefit of this approach over electroplating is that the power sources and plating baths are not needed, reducing the cost of production.

  • Desorption Electrolysis System, Electrolysis Equipment

    In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, AuCN2 is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.
