Dithiophosphate 25S Major component:Sodium dicresyl dithiophosphate Description: Brown to dark brown liquid, specific gravity (20oC) 1.13, PH = 10-13, odorless. Principal uses:Dithiophate 25S is a water solution made from dithiophosphate 25.it is an effective collector for copper,lead sulfide minerals.Because of its weak collective power to zinc sulfide it is usually used in the selective separation flotation of copper and lead sulfides from zinc sulfide minerals.This reagent may be fed to flotation circuit.
