It is notable that the differences in flotation recoveries are 63.74% and 53.92% at molar ratios of 6:1 and 8:1, respectively, showing a tendency of diminution with increasing BHA:DDA molar ratio. The flotation recoveries of spodumene and feldspar are 88.31% and 24.57% at pH 8–9, respectively, at BHA:DDA molar ratio of 6:1.

Flotation tests show that the amine concentration ought to be kept lower than 1.47 × 10−5 mol/l (≈5 ppm) to prevent feldspar loss during metal-oxides flotation stage and hence dewatering ...

Compared to coarse minerals, feldspar slime exhibits low flotation efficiency and selectivity due to its low mass, impact moments, and high interfacial energy . After the flotation with an A-TD collector, the concentrates with 12.95% Na 2 O + K 2 O meet the feldspar specifications of ceramic products, while the mass recovery of …

This paper reviews the beneficiation technology and mechanism of feldspar proposed in the literature to identify the important parameters. This review indicates that crystal structure, monovalent salts, flotation reagents, and particle size distribution are important factors in the process. Environmentally-friendly principle and economic ...

Abstract The flotation process and magnetic separation are the most common methods for feldspar beneficiation containing approximately 0.4% Fe2O3 and 0.04% TiO2. A model MIH (13) 111-5 Induced Roll dry high-intensity magnetic separator was used in this investigation to produce high-quality feldspar concentrate, and …

An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. Froth flotation experiments on a Qtz–Kfs mixture showed that quartz could be selectively floated from Kfs in diluted hydrofluoric acid (HF) using a frother. Similarly, feldspar could be …

The purpose of this research is to recover slime waste from feldspar flotation plant at Attanee International Co., Ltd., Tak province.Slime waste with particle size less than 230 mesh, is found ...

Abstract. Feldspar and quartz are similar in composition and structure, and hence, they exhibit low flotation separation efficiency in acid or alkaline conditions and …

Abstract. Copper oxide minerals are important copper resources, which include malachite, azurite, chrysocolla, cuprite, etc. Flotation is the most widely used method for the enrichment of copper oxide minerals in the mineral processing industry. In this paper, the surface properties of copper oxide minerals and their effects on the …

The result of flotation experiments of the mixed minerals shows that the combination of EDA and PEA can effectively separate the quartz and the feldspar. For the froth products, the quartz content of 2-F-Qtz reaches 97.42% and the SiO grade is 99.12% at a quartz flotation recovery of 70.20%. For the sink products, the feldspar content of 4 …

However, when Orhan and Bayraktar (2006) separated mica from a feldspar ore by flotation with tallow amine acetate as a collector and then separated iron and titanium oxide minerals using sodium oleate, they found that, in the presence of residual amine, co-adsorption of oleate on the feldspar occurred, resulting in the flotation and …

Quartz and feldspar are usually exist in symbiosis in nature, and they are difficult to be separated effectively by conventional physical methods owing to their similarities in crystal structures and surface characteristics. Flotation is the most resultful method, and especially, flotation with hydrofluoric acid (HF) is the most efficient way.

The flotation performance of spodumene and feldspar with four size ranges (0–19, 19–38, 38–45 and 45–75 μm) are investigated in single mineral micro-flotation tests.

This review work reports the recovery of potassium from different rocks and mineral sources. The global demand for potassium is rising consistently due to the growth of agricultural production. ... the mineral surface as is evident from the infrared spectra data.

The most common beneficiation method for feldspar is flotation with a cationic (amine) collector under acidic conditions. However, there are several disadvantages to this, such as environmental pollution …

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 …

A Comparative Study of Quartz and Potassium Feldspar Flotation Process Using Different Chemical Reagents. An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. Froth flotation experiments on a Qtz–Kfs mixture….

Beneficiation methods of spodumene include magnetic separation, gravity separation, and flotation. Since the major gangue minerals of spodumene are quartz and feldspar, flotation becomes the most important way to concentrate spodumene. In this paper, various researches related to spodumene flotation were reviewed.

The micro-flotation results show that NaOL recovered 77% for spodumene and 37% for feldspar, while BAA recovered 87.87% for spodumene and 37.89% for feldspar. Afterward, they conducted tests using a mineral mixture to verify the favorable outcome of BAA, obtaining a recovery of 67.37% and a concentrate with 6.07% Li 2 O …

The micro-flotation tests showed that the negative effect of feldspar slime on spodumene flotation could be reduced by using the mixed NaOL/DDA collector with mole ratio of 9/1.
