Description. FIELD OF THE INVENTION. [0001] The present invention concerns an improved flotation process for separating feldspar from quartz within a feldspar ore, wherein a specific combination of flotation reagents is used under acidic conditions, in the absence of hydrofluoric acid. BACKGROUND OF THE INVENTION.

A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby …

The flotation separation of spodumene from feldspar was investigated using a new type of mixed anionic/cationic collector, sodium oleate/tributyl tetradecyl phosphonium chloride (NaOL/TTPC). Microflotation experiments, fluorescence spectroscopy measurements, microcalorimetric analysis, and Fourier transform infrared analysis were …

Potassium feldspars are the feldspar minerals in which the silicate tetrahedral and aluminum tetrahedra are bound with potassium ions, rather than sodium or calcium ions as in the plagioclase feldspar subgroup. The potassium feldspar group is composed of three mineral polymorphs, each having the same chemical composition, but slightly different ...

Fig. 3 shows the flotation recovery of spodumene and feldspar as a function of pH in the single collector NaOL and DTAC. Fig. 3 shows that the best pH range for the flotation of spodumene using anionic collector NaOL is 8–9, as most studies have recorded (Xu et al., 2016b). Because the maximum flotation recovery of spodumene using NaOL …

The primary source of lithium is spodumene, a mineral commonly associated with aluminosilicate minerals like feldspar. Flotation is widely regarded as the most effective method for separating spodumene from feldspar. The efficiency of this separation process is largely dependent on the choice of flotation reagents. In this work, an efficient ...

Flotation has been typically used to obtain high-grade feldspar. • Mixed cationic/anionic collectors represent a promising method for feldspar flotation. • Future …

Description of the results of experiment of magnetic separation on the samples of waste Feldspar -Bujanovac Experiments of the magnetic separation are done on high gradient magnetic separator "SALA-HGMS" model 10-15-20, with different magnetic

Abstract. This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves. Much of the published information on feldspar ...

1957 the flotation process replaced most of the hand cobbing operations. Only a few tons of high potash feldspar are still hand picked in the Spruce Pine area and are ground for special ceramic uses. Description of Feldspar Flotation Plant A flowsheet of a feldspar flotation plant is presented in Figure 2.

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 …

1. SF-type mechanical agitation flotation machine is a self-suction and self-suction mining flotation machine, which can be widely used in the separation of non-ferrous metals, ferrous metals, and ...

the flotation of aluminosilicate minerals such as feldspar and epidote, as they promote the adsorption of collectors on the mineral surface in the form of precipitation or adsorption [18–22]. However, the mechanism of Fe3+ on the surface of feldspar remains largely unclear under natural pH. Therefore, to increase the separation of feldspar from

Cationic flotation of feldspar using amine and HF was used to reduce the quartz content. 2. ... The microscopic description showed that the Marrom-Guaíba granite was constituted predominantly by K-feldspar and amphibole, which agrees with the macroscopic description, having secondarily titanite, apatite, and opaque minerals, and …

The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O). Feldspar-silica22 mixtures can occur naturally, such as in sand deposits, or can be obtained from flotation of mined and crushed rock. 11.27.2 Process Description 1-2
