Application

Sodium Disecbutyl Dithiophosphate (DSP-04) is an aqueous solution of dialkyl dithiophosphate.
It has little or no frothing properties. It is a selective collector towards iron sulphides in an alkaline circuit, usually at slightly lower pH than for xanthates. The main application of this reagent is in the flotation of copper sulphides in the presence of pyrite. It is also an effective collector for gold, silver and sphalerite. In many cases a scavenger collector, e.g. small amounts of xanthate, is used. Other applications of this product are the flotation of metallic copper in a low lime circuit and copper oxides and copper sulphides in a mixed oxidesulphide ore.
The flotation collector requires only short conditioning time and is therefore useful for staged addition. Experience has shown that mixture of alky ldithiophoshate and a xanthate or a mixture of two dithiophosphates is often better than either of the collectors alone. It can be added undiluted or preferably diluted with clear water to 5-20% solutions. It is good practice to stir before use.
Its dosage is usually considerably less than fo rother sulphide collectors. It varies with the type of ore, usually falling in the range of 10 to 50 grams per metric ton ore.
Experience has shown that this collector is effective in the pH range of 4 to 12. Because of its selectivity towards pyrite, it can be used at slightly lower pH than xanthates.

Safety and Handling

DSP-04 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.

Storage

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.
