Flotation of sphalerite and pyrite in the presence of

Jun 01, 2001 Abstract Sodium sulfite was used to improve the separation of copper-activated sphalerite from pyrite in mildly alkaline pH conditions. This improved separation was mainly the result of the much larger depression of the flotation of pyrite than sphalerite.

Separation Process of Chalcopyrite, Galenite, Sphalerite

The size of the coalition of chalcopyrite and pyrite is some coarse. While the particle size of the monomer is fine, the qualified tailing is separated by bulk flotation, then the mixed concentrate of pyrite and chalcopyrite will be regrained and separated. Condition: The collector of chalcopyrite is xanthate or black catching agent.

Flotation of sphalerite and pyrite in the presence of

May 25, 2000 Sphalerite flotation slightly decreases with an increase in sodium sulfite concentration with recoveries afterŽ 8 min of flotation of 88% in the absence and 73% in the presence of 10 mol dm.y3 3 sodium sulfite.

Influence of the Interaction between Sphalerite and Pyrite

Pyrite, a common sulfide gangue mineral, is usually associated with sphalerite. During the selective flotation of sphalerite, pyrite is usually depressed by using lime. In alkaline pH ranges, pyrite surface is more hydrophilic than in acidic or neutral pH ranges due to the formation and adsorption of Fe-hydroxide complexes on the surface [ 8, 9 ].

THERMOMECHANICAL ASPECT OF SELECTIVE FLOTATION OF

sphalerite and pyrite for selective flotation with a thermome-chanical treatment package, including attrition. Under condi-tions being analogues to flotation, effect of attrition on the sur-face of sphalerite and pyrite has been studied with infrared spectroscopy used in analysis of complex multicomponent

Selective separation of galena and sphalerite from pyrite

and sphalerite minerals was evaluated from a pyrite -rich lead zinc sample. An optimum mixture of selective collectors against pyrite and also organic/inorganic pyrite depressants was obtained in the flotation of galena and sphalerite by an experimental mixture design.

New collectors for sphalerite flotation ScienceDirect

Jun 01, 2006 Flotation tests were done on a Canadian ore that contained about 2–3% copper, 7–8% zinc and about 15–20% iron. Chalcopyrite, sphalerite and pyrite were the main sulfidic mineral constituents of the ore. 2.2.1. Procedure for flotation tests

Sphalerite with Pyrite and Galena (#90) Geology

Sphalerite (ZnS), pyrite (FeS 2), and galena (PbS) have at least one thing in common: they are all metal sulfides. Many ore minerals (that is, minerals that contain elements of such value that they are mined as "ores" to obtain those elements) are sulfides.

(PDF) New collectors for sphalerite flotation

Sphalerite was floated without activation by copper sulfate, and the best sphalerite recovery of about 80% (grade 32%) was achieved with N-hydrocinnamoyl-N-phenylhydroxylamine (HCNPHA) 67 g/t...

CHAPTER 7 FLOTATION OF SULPHIDE MINERALS

The species of xanthate responsible for the flotation of pyrite in the presence of short chained xanthates is dixanthogen (X 2) a dimer of xanthate. Dixanthogen is an electrically neutral dimer.

Separation Process of Chalcopyrite, Galenite, Sphalerite

1.2 Bulk Flotation: This method is suitable for the combination of chalcopyrite and pyrite in the ore. The size of the coalition of chalcopyrite and pyrite is some coarse.

Method of floatation of copper-zinc-pyrite ore (versions)

The method of floatation of copper-zinc-pyrite ore includes grinding in alkaline medium, conditioning with reagents collectors and a foaming agent, collective copper-zinc floatation to produce a collective concentrate, containing minerals of copper and naturally activated sphalerite, and tails.

gem-sphalerite History

A flotation plant for concentrating the desire components was installed in 1957, up to 50 tons of the minerals extracted could be concentrated. When reserves started to decrease in 1968, more drillings were done which discovered the existence of a mineralized zone of a 6 meters potency. (Almadén), pyrite (Navajún), sphalerite (Aliva) and

The effect of mode of occurrence of galena and sphalerite

The flotation results shown in Figure 12 indicate that galena and pyrite were the fast floating minerals, while sphalerite was the slow floating mineral. Figure 12 also indicates that approximately 36% of pyrite, 34% of galena and 7.2% of sphalerite were recovered in the first minute of flotation.

The measured lead content of galena was higher than the theoretical percentage (89.90%

Influence of the Interaction between Sphalerite and Pyrite

Flotation tests were conducted in a 40 mL flotation cell with 4.0 g of 0.106/+0.075 mm sphalerite or pyrite sample for each test. In the mixture mineral tests, 4.0 g mineral mixtures with different proportions of sphalerite and pyrite were used.
