actions on flotation of quartz using both anionic and cationic surfactants and polymers. Quartz, clay and other silicate type minerals are almost always present with energy …

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 ...

Hydrogen bonds play an important role in the interaction between surfactants. In this study, the effect of three different ethoxylated alcohols (OP-10, NP-10, AEO-9) on the collecting behavior of sodium oleate (NaOL) in the flotation of quartz was investigated. To explore the mechanism, the hydrogen bond between ethoxylated …

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 …

The flotation separation of magnetite and quartz is a long-term challenge for the beneficiation industry. For high-quartz magnetite, conventional flotation shows poor separation effect, resulting in the …

Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.

Quartz, the second most abundant mineral in the earth's crust, is a gangue mineral in practically every flotation process. Coarse quartz flotation has been a long standing problem in various ...

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 ...

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 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 ...

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 ...

The flow chart of quartz flotation is shown in Fig. 1.A 40 mL XFG tank flotation machine was used to conduct the flotation experiments [19]. 2.00 g of quartz particles and 30 mL of DI water were poured into the flotation tank and stirred to adjust the pulp for 2 min, after which pH regulator, activator (only present in anionic flotation), and …

The recovery of iron from low-grade (31.6% Fe) Muro iron ore was investigated using reverse anionic flotation of quartz.

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 …
