DITHIOPHOSPHATE 25
CAS Number:
Major component: Phosphorodithioic acid bis(methylphenyl)ester.
Molecular Formula: (C7H7O)2PSSH
Structural Formula:
Description:
A brown-black corrosive liquid with a pungent odour, inflammable,
sparingly soluble in water.
Principal uses:
Dithiophosphate 25 combines both collecting and frothing properties.
It is an effective collector in flotation of lead, copper, silver
and activated zinc sulfide minerals. It is usually used in the selective
separation of lead from zinc minerals. In alkaline circuit, it does
not float pyrite and other iron sulfide minerals readily, but in
neutral or acid medium, it is a strong and nonselective collector
for all sulfide minerals. It has specific performances to oxidized
heavy metal ores. Because it is only sparingly soluble in water,
dithiophosphate 25 must be fed in original form to conditioner or
to ball mill.
