The commercial form of the collector (Aerophine 3418A from Cytec Industries) was used. The collector contains ca. 50% w/w of sodium-diisobutyl dithiophosphinate and traces of triisobutyl phosphine sulphide impurity (the rest is water).
Grano et al. (1997a,b) proposed that surface state of chalcopyrite was highly influenced by pulp pH: formation of iron oxyhydroxides on chalcopyrite surface at alkaline pHs has found to inhibit adsorption of DTP and depressed the flotation.

AEROPHINE, AERO and AEROFLOAT collectors (promoters) are used extensively for the flotation of sulfide minerals including copper, gold, lead, zinc, nickel, iron, and many others that provide improved performance, higher selectivity than more traditional sulfide collectors and better overall metallurgical performance.
