The product (sodium disecbutyl dithiophosphate)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 alkyldithiophoshate 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 dosageis usually considerably less than for other 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:
This product 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”
+Store in plastic drums or coated steel drums
This product 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.
