MEI's Barry Wills: Flotation of chalcocite at very low pH
2012-8-21 Chalcocite responds well to flotation. In Nchanga though it is lost mainly to very coarse and very fine size fractions of the concentrator tailings. This is because Nchanga flotation feed contains atypically high proportions of these fractions even at a moderate 55% passing 74 micron grind, a characteristic of Nachanga ore.

2014-4-1 Chalcopyrite and chalcocite do not affect pyrite flotation in the same way in rougher flotation after primary grinding. This is because the galvanic interaction between minerals in both chalcocite–pyrite and chalcopyrite–pyrite systems is weak at coarse sizes with small surface areas.

Chalcocite - an overview ScienceDirect Topics
III.H.2.c Sulfide flotation. Collector adsorption on sulfides can occur by two mechanisms. One mechanism is chemical and results in the presence of a chemisorbed metal thiol compound at the mineral surface. This mechanism occurs with galena (PbS), chalcocite (Cu 2 S), and sphalerite (ZnS). The other mechanism is electrochemical and gives an oxidation product that is the hydrophobic species

2017-11-1 Chalcocite and molybdenite both show better flotability in the presence of BX and Z-200 within the whole pH range of 2–12 (Fig. 3 a and b) with recovery of higher than 85%. When BX is adopted as collector, difference of their recoveries is less than the case of Z-200, which indicates BX shows better collecting property.

2014-5-13 2. Flotation of middling particles (i.e. higher than 200 µm) improves with increased pH. This is true in the case when chalcocite is the major copper mineral. In the case of chalcopyrite ore, a lower pH is more desirable (i.e. 8.5–9.5) because at a higher pH, the flotation of chalcopyrite is decreased, especially for the coarser particles.
