Zinc processing - Ores | Britannica
The theoretical voltage required to deposit zinc from zinc sulfate solution onto a cathode is about twice the voltage necessary to decompose water, so that, in theory, electrolysis should result in the production of hydrogen at the cathode and not the deposition of zinc. When a zinc cathode is used, however, overvoltage prevents the generation of hydrogen, and, hence, zinc is deposited. The hydrogen …

Advantages of Zinc-free Hydraulic Oils - Lubrication
The disadvantages of zinc-based additives include their corrosion of certain metals and environmental impact. Oils with zinc levels that are too high have a history of leading to the corrosion of some metals, such as yellow metals, as they chemically attack the metal surfaces. A number of components even include instructions to avoid zinc-based additized lubricants for this reason. In addition ...
