Substance description/characteristics

  1. Name and other identifiers of the substance:

The substance Zinc, dross is a UVCB (origin: inorganic)

Public name: Zinc dross

Substance identity:
EC number: 273-694-8
EC name: Zinc, dross
CAS number (EC inventory): 69011-50-3
IUPAC name: Scum formed on the surface of molten zinc and zinc alloys
Description: During the melting and alloying phase(s) of Zinc metal ingots-, one produces:
- On the surface of the bath a lighter Zinc/Zinc oxide-rich Intermediate phase,
- In the bag-house filter –cleaning the process gasses-, a similar Zinc/Zinc oxide-rich Intermediate phase.
Due to the addition of especially chosen fluxes, the separation of the drosses from the bath-surface is eased and occurs, at regular intervals. The process gasses are de-dusted in appropriate equipment, including a final bag-house filter. The filter-dust has a composition similar to the surface dross.
Molecular formula:  n.a.
Molecular weight range:  n.a.
