Product details


Molecular Formula: (C7H7O)2PSSH

Main component: Phosphorodithioic acid bis(methylphenyl)ester 

Structural Formula:

Description: A brown-black corrosive liquid with pungent odour, Density(20℃)1.17-1.20g/ml, slightly 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.
