Zinc Top Dross
Zinc dross is generated by the combination of zinc oxide with other impurities such as aluminum, iron, and other alloying elements in the zinc bath that is used for the continuous hot-dip galvanizing line floating on the top of the zinc bath. This dross is collected using dross spoons and put into small dross boxes. Zinc dross is used for recycling of zinc, the production of high-purity zinc oxide, and other applications requiring zinc.
The composition may vary depending on the processing conditions.
