Effects of Interfacial Hydroxylation Microstructure on

Abstract. Quartz, a common inorganic nonmetallic mineral, is usually removed or purified by beneficiation, normally flotation. Given the strong polarity of the quartz surface, it is easy to hydrate to form a 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 Utilization of DTAB as a collector for the reverse flotation

The micro-flotation of quartz particles was performed using an XFG-cell in the presence and absence of BMNBs with Cetyltrimethylammonium bromide (CTAB) as a collector. The Micro-flotation results indicated that 81.60% quartz was floated with both 5 × 10 −4 mol/L of CaCl 2, 2.5 × 10 −4 mol/L of NaOL and 3.0 × 10 −5 mol/L of DDA at pH 9.0, however, less than 10% of quartz was recovered without adding Ca 2+ or only using CaCl 2 and NaOL.

An Assessment of the Role of Combined Bulk Micro- and Nano

The flotation experiments were conducted on high-purity quartz samples taken from Jiangsu province, China. A laser particle size analyzer (GSL-1000, Liaoning instrument research institute Co., Ltd., Dandong City, China) was employed to measure the particle size distribution (Figure 1). According to Figure 1, the quartz sample had a d 50 Another method is to use anion collector for flotation in alkaline medium, with a pH value of 10.5-8 and an upper limit of flotation particle size of 0.8mm.

Separation of feldspar from quartz: Mechanism of mixed

Using pure albite and quartz minerals, the separation of albite from quartz using mixed cationic/anionic reagent schemes is assessed through Hallimond flotation, zeta potential and diffuse reflectance FTIR studies. The reagent schemes are tested in bench-scale flotation for the separation of albite from Greek Stefania feldspar ore.

Adsorption mechanism of mixed anionic/cationic collectors in Muscovite

The flotation performances of muscovite and quartz had been studied using DDA, NaOL and mixed NaOL/DDA with various molar ratios. Fig. 1 shows flotation recoveries of muscovite and quartz as a function of pH in the presence of different collectors. It can be seen that with an increase of pH from 2 to 11, the recovery of Quartz, a common inorganic nonmetallic mineral, is usually removed or purified by beneficiation, normally flotation. Given the strong polarity of the quartz surface, it is easy to hydrate to form a hydroxylation layer, which makes it impossible to float quartz with sodium oleate (OL) used alone.
