Gold plating refining technology has always been an important link in the metal industry. With the continuous progress of technology, the gold plating refining technology is also constantly innovating. At present, the mainstream gold plating refining technology mainly includes chemical dissolution method, electrolysis method and high-temperature smelting method.
Chemical dissolution is a common technique in which a gold-containing coating is placed in a specific solvent to dissolve the gold layer, and then the metal is separated by filtration, precipitation, and other steps. The electrolytic method uses an electric current to dissolve the gold plating layer and then separate the metal in the electrolytic cell. The high-temperature smelting method is to place gold-bearing materials in a high-temperature smelting furnace to melt the metal, and then separate the metal by physical or chemical methods.
With the improvement of environmental awareness, modern gold-plating refining technology also pays more attention to green environmental protection. Some new technologies use environmentally friendly solvents, which reduce environmental pollution and improve efficiency. In addition, the application of automated equipment also makes gold plating** refining more efficient and accurate.
In the future, with the continuous development of science and technology, gold-plated will be mentioned.
The refining technology is expected to be further improved. New technologies that are more efficient, low-cost, and environmentally friendly may emerge to promote the gold plating industry towards a more sustainable development.
