The substance Zinc, dross is a UVCB (origin: inorganic)
Public name: Zinc dross
|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 weight range:||n.a.|
