Danafloat™ 123 mineral collector

Danafloat 123 is the most selective collector in the Danafloat dithiophosphate range. It has no frothing characteristics. Being a selective reagent Danafloat 123 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 Danafloat 123 is used.

Danafloat 123 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.

Danafloat 123 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 Danafloat 123 varies with the type of ore, usually falling within the range of 20 to 100 grams per metric ton ore.

Danafloat 123 is effective in the pH range of 4 to 12. Because of its selectivity against iron sulphides, Danafloat 123 can be used at lower alkalinity than xanthates.
