Aerophine 5100
AERO 5100 promoter is a modified version of IPETC, with incorporation of an allyl group attached to the nitrogen, which increases its collecting power but retains its known selectivity against iron sulfide minerals. Due to its very low solubility in water, it sometimes has a flattening effect on the froth, especially if overdosed. The optimum point of addition – to the grind, to a conditioner, or staged-addition should always be determined by experiment. If a flat, dry froth is still a problem, the conjoint use of a small amount (10% to 20% of the AERO 5100 dosage) of a short-chain dithiophosphate such as Sodium AEROFLOAT or AEROFLOAT 208 promoter, is often helpful The principal uses of AERO 5100 promoter are in the flotation of copper, activated zinc, and precious metals. It is an extremely poor collector for galena and is therefore an excellent choice for floating ores which contain only nuisance amounts of lead, or for selective flotation of copper in Cu-Pb-Zn ores
