The Recovery System is a simple thermo-mechanical device designed to allow in-house recovery of particulate zinc from skimmings produced during the General Hot Dip Galvanizing process. Financial Value. Skimmings produced during galvanizing have high value as a result of the free zinc contained in them. The traditional methods of realisng this financial value has either been to feed them back into the kettle or to sell them to a trader for a cash return This is generally expressed as a given percentage of the LME published price for zinc, normally 45-55% of LME. Analyses of the skimmings produced have shown that the free zinc available for recovery is about 70% by weight from most general hot dip galvanizing processes. This can be as high as 85% from spin/centrifugal galvanizing an...
