ZINC ELECTROPLATING Zinc Electroplating - Pavco

Zinc passes over an overflow weir and is tapped off and conveyed to the zinc reinery or casting area. ISF zinc from the furnace contains about 1-1.3% lead and may be reined by distillation to produce better than 99.95% purity zinc. Metallic cadmium and other valuable metals may also be recovered in the reining process. Secondary production

Sep 18, 2009· A "7-tank process" is simply a process where parts are immersed in seven tanks sequentially. Normally, a zinc phosphating process is done in 7 steps while the simpler iron phosphating pretreatment process is done in 3 steps or sometimes 5 steps. So when you ask about a 7-tank process for pretreatment, you are probably asking about zinc phosphating.
