Quartz is often symbiotic with feldspar silicate minerals, which is difficult to separate and purify because of their similar physical and chemical properties. Flotation is the most effective method for the separation of quartz and feldspar. The main flotation methods for the separation of quartz and feldspar, such as hydrofluoric acid method, …

It also shows that an increase in the amount of Brij 58 has a strong positive effect on the flotation of quartz. At 100 g/t Brij 58 an increase from 67.8 to 108.5 kg/t HF increases the recovery of quartz by approximately 36%, while an increase from 67.8 to 217 kg/t HF increases the recovery of quartz by more than 60%, from 52% to 83.5%.

Specifically, the flotation behavior and flotation kinetics of quartz with two different roughness values altered by acid etching were investigated under the …

Quartz is also a typical gangue mineral in many flotation systems such as beryl (Fuerstenau et al., 1965b), sphalerite (Duarte and Grano, 2007), and other sulfide minerals. Although quartz possesses hydrophilic surface properties in nature and cannot be floated by anionic surfactants alone at any pH, hydrophobicity can be induced by adding ...

The flotation response of malachite, calcite and quartz to bis (2-ethylhexyl) phosphate (DEHPA), dibutyl phosphate (DBP) and tributyl phosphate (TBP) was evaluated by micro-flotation experiments. The results showed that DEHPA exhibited an impressive flotation selectivity for malachite against calcite/quartz in the pH range of 6.0–9.0 and ...

The affinity between the ultrafine kaolinite of the slimes with the corn starch is harmful to the reverse flotation of quartz, as the starch has an important depressing action over the hematite ...

To investigate the flotation separation behavior of petalite and quartz, various methods were employed in this study. These included micro-flotation experiments, a contact angle analysis, zeta potential analysis, Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS) to explore the separation …

The results demonstrated that it was more likely for quartz with higher fluid inclusion abundance to connect with Fe3+ sufficiently to achieve a high level of flotation …

Flotation experiments performed on a quartz-feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid (HF) simply by the aid of a frother. High grades and good recoveries were obtained for both quartz and feldspars. A feldspar concentrate of 99.9% at a recovery of 95.6% was ...

In general, the flotation of quartz has two common methods: cationic flotation using fatty amines, quaternary ammonium salts, ether amines, etc., and flotation with metal ions activation and using anionic collectors, such as sodium oleate, sodium …

quartz-DAH flotation. The results showed that temperature of the suspension sharply increased from 23. up to 75 °C at the end of 10 min of co nditioning at 150 W ultrasonic power. The flotation ...

The poor flotation of coarse quartz particles (>0.150 mm) causes significant problems in various iron ore flotation circuits by contaminating the concentrate. The study evaluated the performance ...

It is difficult to separate smithsonite from quartz with metal ion activation through flotation using sodium oleate (NaOL) as the collector. The inevitable Zn 2+ in the flotation process of zinc oxide ore makes the separation of smithsonite and quartz more difficult. Thus, this study investigated the use of phytic acid (PA) as a flotation depressant to separate …

In this study, the effect of ultrasound (US) on the quartz-amine flotation system was investigated in detail by considering various surface chemistry techniques. The effect of ultrasound on particle size, shape factor, and surface roughness were characterized by using Brunauer-Emmett-Teller (BET) surface area measurements and scanning electron ...

The flotation separation of magnetite and quartz is a longterm challenge for the beneficiation industry For highquartz magnetite, conventional flotation shows poor separation effect, resulting in the waste of resources and low flotation efficiency In this paper, dodecylamine acts as a collector and Al(III) ions in water act as a depressant to ...

Therefore, although Fe(III) effectively improved the flotation of spodumene, it was not beneficial for the flotation separation of spodumene from feldspar and quartz. When Ca(II), Mg(II), and Cu(II) were used as activators, the adsorption amounts of α-BDDA on spodumene were significantly higher than those on feldspar and quartz, which led to …

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 data and proposed mechanisms and reinterpreting some of the past …

The flotation responses of quartz and feldspar with alkylsulfonates' collectors in the presence of some alkaline earth metals were studied. The activation mechanism in these systems is discussed in terms of hemimicellization and surface precipitation of neutral component of cation-sulfonate complex, e.g. Ca(OH)RSO 3.. …
