Chinese produced Chemical Mining Reagent Sodium Diethyl Dithiophosphate
Sodium Diethyl Dithiophosphate
Classification: General Reagents
Cas No: 3338-24-7
Appreance: Yellow brown liquid
Solubility in water: Complete
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.

Safety and Handling
DSP-01 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
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.
