The substance Flue dust, zinc-refining is a UVCB (origin: inorganic)
Public name: waelz oxide
|EC name:||Flue dust, zinc-refining|
|CAS number (EC inventory):||69012-63-1|
|IUPAC name:||Flue dust, zinc-refining|
|Description:||Zinc bearing materials and reducing agents (i. e. coke) are blended, wet and fed to a furnace at high temperature causing fuming of zinc
Air oxidizes the zinc in the gas-phase to solid zinc oxide and entrains it together with some particles from the feed; the fume is collected in the gas-cleaning system OR
Material is produced in a blast furnace where there is no oxidising atmosphere. Chemical reaction of the zinc takes place in the wet gas cleaning system (with water)
Flue dust is collected in bag-house filters or wet gas cleaning system. It is a zinc oxide rich material containing some impurities and halogens.
|Molecular weight range:||n.a.|
Flue dust, zinc refining has 2 composition ranges, one of which has very low cadmium and nickel. It will thus have also 2 classifications
