· The zinc electroplating process requires a specialized electrolyte solution for the substrate to be immersed into. This plating bath consists of a zinc metal ionic solution as well as various chemicals to assist in the plating process. The proper solution will help produce the required chemical and physical properties of the finishing plating and are often categorized into two types of baths

Cyanide Process – Extraction Of Gold Through Cyanidation. Gold is usually found in low concentration in the form of ore which is mined. Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions

The Merrill–Crowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores. It is an improvement of the MacArthurForrest process, where an additional vacuum is managed to remove air in the solution (invention of Crowe), and zinc dust is used instead of zinc shavings (improvement of Merrill).

That ends our explanation of the zinc plating process. Remember, zinc is usually alloyed with other metal types, which can lead to better performance than when zinc is plated alone. Gold jewelry, for instance, is often a mixture of gold and various other metals, including zinc, nickel, copper and silver.

Zinc processing Zinc processing Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world''s output originates in North America and Australia. The common zinccontaining minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine
