Product Detail

Product Tags


Sodium Diisobutyl Dithiophosphate (DSP-03) is an aqueous solution of dialkyl dithiophosphate. It has practically no frothing characteristics. It is fast and compared to other thiol collectors more selective in the flotation of copper sulphide in the presence of zinc and of iron sulphides and copper activated zinc sulphides from iron sulphides. Other applications are flotation of copper activated iron sulphides, flotation of nickel-bearing minerals, antimony minerals, chalcocite and for improvement in the recovery of precious metals, e. g. gold, dilver, platinum.
Sodium Diisobutyl Dithiphosphate floats oxide copper minerals as well as sulphide copper in a sulphide-oxide ore very well. This collector has found application in the bulk flotation of copper and cobalt minerals in conjunction with other thiol collectors, usually at neutral pH. It requires only very short conditioning time and is therefore useful for staged addition. It can be used alone or in some cases in combination with an auxiliary collector, such as xanthates.
Experience has shown that a mixture of alkyldithiophosphate and a xanthate is often better than either of these two types of collectors alone.
Sodium Diisobutyl Xanthate can be added undiluted or preferably diluted with clear water to 5-20% solutions. It is good practice to stir before use. The dosage of Sodium Diisobutyl Xanthateis usually considerably less than for other sulphide collectors and varies with the type of ore, usually falling within therange of 10 to 50 grams per metric ton ore. Experience has shown that DSP-03 is effective in the pH range of 4-12. Because of its selectivity towards iron sulphides, the mining reagent can be used at slightly lower pH than xanthates.

Safety and Handling

DSP-03 is manufactured under carefully controlled conditions. However, to varying degrees they can be considered harmful and therefore before handling this product always carefully read and understand the MSDS for this product.
This flotation collector causes irritation to eyes and skin. Safe handling includes the use of safety glasses, natural rubber gloves and protective clothing.


Store in a dry and well-ventilated place away from heat and sunlight after the principle “first in/first out”.
Avoid freezing
Store in plastic drums or coated steel drums

Environmental Impact

It is biodegradable. The majority of the collector is tied up with the concentrate and is destroyed in the subsequent processing operations. The remainder is transferred to the tailings . Release into the water systems should be avoided.
