Abstract

Many metal product surface treatment industries face many problems related to the application of environmental standards and the commitment to preserve them and the ability to use environmentally friendly alternatives, due to the lack of economic resources and the lack of technological development in finding appropriate solutions, reuse and recycling of wastes resulting from surface finishing operations in general and electroplating in general. Despite the availability of modern technology in some major industrial establishments, environmental alternatives have not entered into actual application in most of these establishments due to their weak effectiveness compared to the processes that are actually applied and which have great harm to different environments, especially processes that depend on cyanide in electroplating. Gold plating processes are also considered hey are widely used in covering metal products, especially jewellery, jewellery, tableware, utensils ... and others. Therefore, the use of non-cyanide environmental alternatives for gold and silver plating systems will reduce many pollutants that are harmful to different environments of the product, especially industrial ones.
