Flotation Behavior, Collector Adsorption Mechanism of Quartz and Feldspar-Quartz …

 · The froth flotation results show that the flotation recovery of quartz is 97.79% and that of FQA is 19.30% at pH 9.00–9.50 with 10 −4 M PEA when the particle size ranges from 150 to 270 μm. The results of batch flotation, ICP-OES and XRD analyses show that the first flotation product is almost quartz, while more feldspar and little quartz exist in the sink product when compared with the ...

Metal ion activation in xanthate flotation of quartz

FLOTATION OF QUARTZ by M. C. Fuerstenau, J. D. Miller, R. E. Pray and B. F. Perinne Quartz cannot be floated with potassium amyl xanthate as collector at any pH. Complete flotation is achieved with certain minimal additions of amyl 5.8 to 8.5 7.5 to 8.1. ...

Investigation of quartz flotation from decarburized vanadium …

Investigation of quartz flotation from decarburized vanadium bearing coal 757 Materials and methods Materials The vanadium-bearing stone coal was collected from Teng-da Mining and Metallurgy Co. Ltd., Hubei, PR China. Around 200 kg of representative ore

Non-HF collectorless flotation of quartz

 · Pure mineral flotation experiments have demonstrated that quartz can be floated without a collector, in solutions containing an inorganic acid (e.g. H 2 SO 4) and sodium fluoride (NaF). Excellent quartz recoveries, similar to that of previous investigations with aqueous solutions containing hydrofluoric acid (HF), have been achieved with lower ...

Utilization of DTAB as a collector for the reverse flotation separation of quartz …

 · Reverse flotation desilication is an indispensable step for obtaining high-grade fluorapatite. In this work, dodecyltrimethylammonium bromide (DTAB) is recommended as an efficient collector for the reverse flotation separation of quartz from fluorapatite. Its collectivity for quartz and selectivity for fluorapatite were also compared with figures corresponding to the conventional collector ...

Flotabilities of Iron Minerals and Quartz in Flotation System of Dodecylamine …

In flotation system of dodecylamine, this paper studied the flotation properties of single minerals such as magnetite, martite and quartz firstly. On this basis, the influence of siderite to flotation efficiency of martite-quartz and magnetite-quartz mixed ores was discussed. The result shows that siderite will seriously effect on the flotation ...

FLOTATION OF QUARTZ AND HEMATITE: ADSORPTION …

The flotation response of quartz and hematite as a function of cationic and anionic collector concentration at pH and the pH values varied from 6.0 to 6.3 are displayed in Figure 2. The onset hemi-micelle formation for quartz (refer Figure 2A) with C

Mechanisms of Dodecylamine Flotation of Quartz: Mineral …

Primary monoamines have been long used and studied as flotation collectors for quartz. In the past several mechanisms have been proposed to explain the manner in which the amines adsorb onto and render the mineral hydrophobic and, thus, floatable. From past ...

Effect of Mn (II) on quartz flotation using dodecylamine as …

 · Quartz is, in most cases, the major gangue mineral found in the manganese ore. Mn iron, dissolved from the surface of ore, will determine the interfacial properties of the particles and, thus, their flotation behavior. In this work, the effect of Mn2+ on quartz flotation was investigated through flotation tests. It was found that quartz can be depressed with Mn2+ and floated with dodecylamine ...

Minerals | Free Full-Text | The Effect of Quartz on the Flotation of Fine Wolframite with Octyl Hydroxamic Acid

 · The influence of quartz on the flotation of fine wolframite using octyl hydroxamic acid (OHA) as the collector was investigated by micro-flotation tests, inductively coupled plasma (ICP) measurements, adsorption experiments, zeta potential, and Fourier transform infrared spectroscopy (FT-IR) analysis. Micro-flotation tests showed that a large difference in floatability existed between fine ...

FLOTATION OF SERPENTINITE AND QUARTZ USING …

Flotation of 609serpentinite and quartz using biosurfactants The mineral samples were dry ground using a porcelain ball mill and then wet sieved. The +125 - 250 µm fraction was used for microflotation experiments. The particle size distribution

Flotation of quartz from quartz-feldspar mixtures by the HF …

 · Quartz can be floated from feldspar in diluted HF solutions simply by the aid of frothers. • There is a high flotation separation selectivity between quartz and different types of feldspar. • A feldspar concentrate of 99.9% at a recovery of >95% was produced. • The

Research on Flotation Mechanism of Quartz Using Magnesium …

ZETA potential of quartz surface show positive charge, and the recovery rate of the quartz is corresponding to the maximum within pH=10-12. Combined with the solution hydrolysis of magnesium ion, it can be determined, Mg (OH)+ is the main active ingredient that activate flotation of quartz in the system of anionic collector dodecyl sulphate ...
