Copper Flotation - Mineral Processing

19/03/2017  The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation

15/06/2018  A new flotation tailings treatment process was developed for efficient Cu recovery. • An efficient Cu dissolution was achieved in an H 2 O media in presence of pyrite.. The dissolution mechanism of CuFeS 2 has been confirmed to be a multistage reaction.. Fe was always co-dissolved with Cu following a linear relation of C Fe = 38.393 × C Cu.. Over 91% Cu was extracted from

Copper Sulfide Flotation - Mineral Processing Metallurgy

19/03/2017  Standard “Sub-A” Flotation Machines are used for both the rougher and cleaner circuits, where their cell-to-cell principle gives both high recovery and a good grade of concentrate. The rougher concentration is accomplished in 6 or 8-cell flotation machines, with the concentrate from each going to a separate bank for cleaning and re-cleaning. No. 30 “Sub-A” Flotation Machines are ideal ...

Table 6 shows the overall copper recovery (64.3%), previously determined by mass balance adjustment around the (12), from data presented in Table 5, and the pulp zone recovery (73.1%) calculated by Eq. Froth zone recovery(3) as a function of the overall recovery and the froth recovery. During this test, the froth depth was 15 ± 1 cm, the superficial air rate was 1.31 cm/s, then assuming a ...

Froth Flotation - an overview ScienceDirect Topics

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now widely used for separations such as the beneficiation of ...

To support the high SG of the native copper and to overcome the large dosage of collector, they used a very strong mixed polyglycol frother to provide a strong froth base. You may find that potassium amyl xanthate to be too non-selective in your application, but I would consider testing some dodecyl mercaptan, which is generally cut by chemical suppliers in some type of oil, as a supplemental ...

Froth flotation - Wikipedia

Grade-recovery curves are useful tools in weighing the trade-off of producing a high grade of concentrate while maintaining as low of a recovery rate as possible, two important aspects of froth flotation. These curves are developed empirically based on the individual froth flotation process of a particular plant. As the curves are shifted in the positive x-direction (to the right) and the ...

01/04/2019  It is well known that in the froth flotation process, recovery is a strong function of particle size. Fig. 1 shows characteristic data from Gaudin et al., 1931, Jowett, 1980, for the flotation of galena. Similar behaviour is observed with other sulfide minerals. Recovery is high between 10 and 100 µm, but outside this range, it drops quite rapidly. The reasons for the reduction in recoveries ...
