Froth flotation is a highly effective technique for mineral separation, which involves the addition of collectors to promote hydrophobic interactions between minerals and collectors, thereby improving the efficiency of mineral separation [8], [9], [10].Xanthates are the major collectors utilized for the recovery of chalcopyrite owing to their superior collecting ability …
The strength and stability of the froth are important when floating free gold. There appears to be a preference for polyglycol ether–based frothers on most gold plants in combination with one or other frothers. ... For a short period during 1987 and 1988, a differential flotation …

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO.sub.3.sup.- ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate …
Flotation is the principal process for preconcentration of the sulphides for subsequent smelting, roasting or hydrometallurgical treatment. However, the selective separation of chalcopyrite and pyrite minerals by froth flotation is often problematic, due largely to the number of minerals involved and the nature of the associations of these ...
Nowadays, froth flotation of chalcopyrite ore has developed a large number of reagents that make it possible to improve the mineral's buoyancy conditions, both in the …
A RAFT polymer, poly(CA 4-co-ACOEA 14), was synthesized incorporating O-ethyl acetylcarbamothioate (R–O–C(═S)–NH–C(═O)–CH 3) functionality for selective binding and cardanyl acrylate moiety as a hydrophobic component, with the goal of selective separation of chalcopyrite from pyrite. Laboratory experiments encompassing flotation ...

The more flotation collector you have on, the higher you will need to increase that pH for effective pyrite depression. You also need to insure your pyrite and copper minerals are well liberated for good chemical separation …
Gold grains are observed in a variety of forms, such as coarse-liberated native gold grains, and ultra-fine grains associated with sulfide or non-sulfide mineral particles, in the form …
A froth flotation process for effecting separation of arsenopyrite mineral from pyrite mineral comprising conditioning at pH less than 8 and at a temperature of at least 30 0 C an aqueous pulp containing particles of said arsenopyrite and pyrite minerals, the conditioning being conducted with a sulfitic depressing agent providing HS0 3 O ions ...

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a …
The effect of NBIB concentration and pH on the flotation recovery of chalcopyrite and pyrite is shown in Fig. 2.It can be seen in Fig. 2 (a), that as the NBIB concentration increased from 0.53 × 10 −4 mol/L to 2.66 × 10 −4 mol/L, the recovery of chalcopyrite increased from 82.67 % to 85.41 %, and the recovery of pyrite increased from 7.69 % to 54.67 %.
The separation of chalcopyrite and pyite is not fully solved, and thus more efficient depressants are still needed in industry. This paper used potassium permanganate (KMnO4) as a pyrite depressant to separate pyrite from chalcopyrite. Flotation and contact angle results indicated that pyrite could be depressed by KMnO4 at pH 7, while KMnO4-treated …
