Sodium Diisopropyl Dithiophosphate
The mining reagent is an aqueous solution of dialkyl
dithiophosphate. It is the most selective collector in the
dithiophosphate range. It has no frothing characteristics. Being a
selective reagent, it is useful as a rougher collector producing a
high grade first concentrate. For optimum recovery a scavenger
collector, e.g.a stronger dithiophosphate or a xanthate in
conjunction with it is used.
Sodium Diethyl Dithiophosphate (DSP-01) is very selective towards
pyrite and other iron sulphides and is therefore used in the
flotation of copper sulphide mineral and Cu-activated sphalerite,
particularly in the presence of pyrite. It does not float lead
sulphide. The collector being a selective reagent is applicable on
easy floating liberated copper sulphide like Skim-Air flotation in
the grinding circuit.
It can be added undiluted or preferably diluted with clear water to
5-20% solutions to better control the dosage. It is good practice
to stir before use.
The dosage of this product varies with the type of ore, usually
falling within the range of 20 to 100 grams per metric ton ore.
It is effective in the pH range of 4 to 12. Because of its
selectivity against iron sulphides, It can be used at lower
alkalinity than xanthates.
