23/05/2021· Zinc Ash / Zinc Waste in Hot dip Galvanizing Finishing. A company makes a device that recovers about 70% metallic zinc from dry ash. The recovered zinc has about the same composition as the kettle zinc except it is 10 times more concentrated in iron (e.g. 0.4% as compared to 0.04%). This gives slightly more dross but is not a problem. Online
