Keywords Flotation, Feldspar, Mica's minerals, Ceramics, Glass 1. Introduction Feldspar is one of the most common minerals in the world where it forms about 60% of the rocks of the earth's crust [1-6]. Orthoclase (K-feldspar), albite (Na-feldspar) and anorthite (Ca-feldspar) are the most widespread feldspar minerals.

Herein, several experimental methods, including flotation experiments, zeta-potential detection, microcalorimetry detection, XPS analysis and FTIR measurements, were used. The flotation tests showed that dolomite and potassium feldspar can be successfully removed from apatite simultaneously when the molar ratio of DTAB to NaOL was 2:1 with …

The collector dosage was changed from 97 to 291 gm/ton. The used frothing agent was pine oil. Sulfuric acid was used as a pH modifier. After flotation of mica's minerals, the tailings were dewatered and washed many cycles to disengage residual reagents on particles [9]. The tailings were taken as a feed sample for the flotation of …

Then, the quartz-feldspar separation was achieved using NaOH as pH adjuster, MgCl 2 as activator, and NaOT as collector. The results of the flotation test showed that the yield of quartz products was 24.51% with a grade of 96.04% SiO 2, and the yield of feldspar products was 41.77% with a grade of 14.06% K 2 O and Na 2 O. The …

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 and equipment corrosion. In order to resolve such problems, it is important to study the flotation of feldspar using anionic collectors under …

Feldspar minerals (KAlSi 3 O 8, NaAlSi 3 O 8, CaAl 2 Si 2 O 8) are the most abundant of aluminosilicate rock forming minerals, comprising 60% of the earth's crust.They are widely applied in the production of glass, ceramics, and as fillers and extenders [1,2] in the paper and paint industries.In order to improve the purity or the whiteness of feldspar, …

Multistage flotation circuits were employed to remove mica, ferruginous, heavy coloured contaminants and free silica from the ground feldspar sample. Most of the reagents used are local products ...

Considering that metal ions, such as Si 4+ and Al 3+, are abundant in the spodumene–feldspar flotation system, SA is a potential depressant for this system. However, there are no published papers concerning the use of SA as a green and efficient depressant in the spodumene–feldspar system. ... mica and feldspar from a lithium …

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 …

The slime waste from feldspar flotation plant at Attanee International Co., Ltd. in Thailand, contains orthoclase, albite, quartz, and ferrous impurity minerals such …

1. Flotation separation of mica minerals and silica sand. Mica dissociates a large number of anions O2- and F- with extremely low zero electric points. After being exposed to the layered structure, they can be recovered with cationic collectors in a wide pH range (pH=2-13). The pH range of feldspar in the cation collection system (pH=4-11) is ...

Samples from the pyrophyllite reserves in the Malatya–Pütürge region, used in the production of the whitest cement in Europe, were beneficiated using flotation. The mineralogical composition of the natural pyrophyllite, as determined using X-ray diffraction, includes pyrophyllite, kaolinite, quartz, illite–mica and feldspar.

Early representative works include Flotation written by American chemist A.M. Gordon ... wolframite, malachite, rare earth minerals, and uranium ore; nonmetallic minerals: apatite, fluorite, mica, graphite, sulfur, feldspar, barite, diamond, and quartz; and soluble salt minerals: potassium salt, rock salt, etc. In addition, another important ...

A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and …

The selectivity in flotation separation of spodumene from other pegmatic aluminosilicates such as feldspar and mica, using a single fatty acid anionic collector, is found to be very difficult. It is attributed to the same surface Al …

In this approach, mica was first floated by adding Na 2 CO 3 as pH adjuster and sodium oleate/octanol with mass ratio 9/1 (NaOT) and dodecylamine acetate as mixed collector. Then, the quartz-feldspar separation was achieved using NaOH as pH adjuster, MgCl 2 as activator, and NaOT as collector.

In feldspar flotation, the minerals causing slime formation have similar mineralogical properties to other minerals trying to be floated during the mica and and heavy mineral removal flotation stage. This causes unsuccesful selective separation and also excessive reagent consumption [ 19, 27, 30, 31, 32 ].

In this paper, the flotation separation of quartz and feldspar was studied with CaCl 2 as activators and mixed sodium oleate/ dodecylamine (NaOL/DDA) collectors under alkaline condition, and the action mechanism of mixed NaOL/DDA collectors on the quartz and feldspar surfaces were systematically explored. The results of micro-flotation test …

The flotation separation of spodumene from other complex aluminosilicate minerals such as feldspar and mica, is problematic, due to their same active Al site for interaction with anionic collectors (Rai et al., 2011). In practice, the general method to accomplish effective spodumene flotation is to add amount of depressants associated …
