The Flotation of Pyrite using Xanthate Collectors
The flotation properties of pyrite were found to be significantly influenced by va~iations in the pH. In acidic solutions the pyrite floatability is very high, and recoveries of 95% could be achieved using only a frother. A sharp decrease in floatability was observed in alkaline ...
The effect of lizardite surface characteristics on pyrite ...
Oct 15, 2012 · In Fig. 2, the flotation recovery of pyrite can be observed as a function of pH in the absence and presence of lizardite mineral.The flotation recovery of pyrite in the absence of lizardite is very high (>85%) under acidic and neutral conditions. As the pH was increased, pyrite recovery decreased due to formation of hydrophilic iron oxy-hydroxy species on the surface .
Pyrite Depression in Copper Flotation
The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite-copper, you need to bring the plant’s pH up to the other side (right side) of the PYRITE curve. 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 ...
The effect of saline water on copper activation of pyrite ...
Jan 15, 2019 · Pyrite is usually perceived as a gangue mineral and removed by flotation to minimize its contamination in copper concentrates (Wang and Forssberg, 1991). In froth flotation, hydrophobic particles are supposed to attach to the rising bubbles, float to the pulp surface and are recovered as a froth product (Hirajima et al., 2016).
The effect of galvanic interaction between chalcopyrite ...
Due to the natural hydrophobicity of sulfide minerals, the flotation response of chalcopyrite and pyrite is investigated in the collectorless system, and the results are shown in Fig. 6(a)-(b). Meanwhile, the flotation recovery of chalcopyrite and pyrite was discussed with SBX as a …

Below is a graph showing pH VS pyrite recovery at various collector addition rates. It is also used to prevent flotation of sphalerite by copper activation in the presence of Tennantite/Covellite in the ore. For pyrite flotation, you see maximum iron/pyrite depression using Sodium Metabisulfite/MBS takes effect at …

Jan 15, 2019 · The effect of PBX concentration on the flotation performance of different-sized galena and pyrite at pH 7 is studied and the results are shown in Fig. 2.As shown in Fig. 2, the flotation recoveries of these two minerals increased quickly with the increase of PBX concentration.When PBX concentration reaches 0.5 × 10 −4 mol/L, the recoveries for both galena and pyrite reach their …
Pyrite - an overview | ScienceDirect Topics
M.B. Goldhaber, in Treatise on Geochemistry, 2003. 7.10.3.2 Pyrite. Pyrite is the dominant solid-phase form of sulfur in organic-matter-bearing marine sediments. Pyrite is cubic FeS 2.It can have a wide range of crystal morphologies (Gait, 1978; Love, 1967) although only a subset of these are recognized from sedimentary environments.Canfield and Raiswell (1991) review pyrite morphology in ...
INFLUENCE OF PYRITE CONTENT ON THE FLOTATION OF ...
The flotation experiments for the various blends were repeated several times in order to assess reproducibility of the results. As an example, values of chalcopyrite (Cp) and pyrite (Py) recovery after 10 min of flotation, and the first order flotation rate constant (k) for three tests with 20% pyrite content are summarised in Table 2.

The flotation results showed that coarser serpentine possessed a weaker depression effect on the pyrite flotation process, and the use of KAl(SO 4) 2 ·12H 2 O could efficiently limit the detrimental effect of fine serpentine on pyrite with a maximum increase of pyrite recovery from 14% to 86% at pH 9.0.
