Substance description/characteristics

  1. Name and other identifiers of the substance:

The substance Slimes and Sludges, zinc sulfate electrolytic  is a UVCB (origin: inorganic)

Public name: lead manganese cellmud

Substance identity:
EC number: 273-742-8
EC name: Slimes and Sludges, zinc sulfate electrolytic
CAS number (EC inventory): 69012-43-7
IUPAC name: Product resulting from cleaning anodes and electrolyzing cells in an electrolytic zinc plant, with zinc sulfate. Consists primarily of manganese oxide, lead sulfate and calcium sulfate.
Description: During the Zinc electrolysis,  insoluble oxy-sulphates (i.e. Lead- & calcium-sulphate and Manganese di-oxide) can be formed at the Lead-anode surface ; part of it falls down in the cells another part sticks to the Lead-anode surface and is separated during the anode-cleaning steps
The Pb.Mn.cellmud is regularly collected from the bottom of the cells and from the anode-cleaning devices, is washed and filtered.
Molecular formula:  n.a.
Molecular weight range:  n.a.
