Danafloat

Danafloat™ 507 mineral collector

Danafloat 507 is an aqueous solution of dialkyl dithiophosphate and thionocarbamate.

Danafloat 507 is normally added to the grinding circuit or in a conditioner and it has no or
very little frothing action.

Danafloat 507 offers good selectivity of mineral over pyrite and has been used in applications involving chalcopyrite, bornite, chalcocite and covellite copper ores. It has also found use in a mixed oxide-sulphide copper ore in conjunction with xanthate. Other applications are in the flotation of galena and Cu-activated sphalerite. Danafloat 507 is a good collector for tetrahedrite.

Danafloat 507 is a very fast and quite powerful collector and it should be used in smaller quantities than xanthate.

Danafloat 507 should be added undiluted. The dosage of Danafloat 507 varies with the type of ore, but is normally lower than for xanthates. Recommended dosage is between 10 and 50 grams per metric ton ore.

Danafloat 507 is normally used in the pH range from 4 to 12.
