Dithiophosphate 25 Major component: Dicresyl dithiophosphoric acid Description:: Pungent dark brown liquid, corrosive, density (20 ℃) 1.17-1.20g/cm3, 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 alkali circuit,it does not float pyrite and other iron sulfide minerals readily.But in neutral or acid medium,it is a strong and non-selective collector for all sulfide minerals.Because it is only slightly soluble in water,dithiophosphate 25 must be fed in origin form to conditioner or to ball mill. Xanthate stronger than its selectivity, stability, better than the xanthate difficult to oxidation.Specifications:Dicresyl dithiophosphoric acid content 60%-70% Cresol and other components:content 30%-40%.
