Large reserves of feldspar ore exist in the Aegean region of Turkey. The main colored impurities in these ores are iron- and titanium-bearing minerals such as anatase, rutile, sphene and ilmenite. In this study, a potassium feldspar ore containing mainly quartz and coloring impurities was subjected to beneficiation tests involving …
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, …
The largest feldspar reserves of Turkey are located in the Çine-Milas Province. The main impurities of these ores are described as titanium and iron oxide minerals such as anatase, rutile, ilmenite, sphene, magnetite, hematite and limonite. In Çine-Milas deposits, a considerable amount of feldspars are not evaluated and disposed due to the high content …
The quality of feldspar is typically judged on its Na/K ratio and the coloring impurities such as Fe and Ti. Typically K-feldspar concentrates must contain a minimum of 8% of K 2 O and a maximum 4% of Na 2 O to meet the requirements of the ceramics industry. As deposits containing high quality Na-feldspar or K-feldspar are becoming …
The dedusting tailings (see Table 1) differ from feldspar raw materials by a heightened weight content of iron oxides (1.26%), and the potassium modulus is the ratio K 2 O/Na 2 O > 2. This difference, in combination with a fine fraction, should improve the ceramic properties.

Medium and highly sulfidic tailings are high-volume wastes that can lead to severe environmental damage if not properly managed. Due to the high content of sulfide minerals, these tailings can undergo …
In the system of CaO-Al 2 O 3-SiO 2 phase diagram, using vanadium-titanium magnetite tailings (VTMT), feldspar tailings (FT), and kaolinite-type pyrite tailings (KTPT) as raw materials, the ceramics have been prepared by introducing SiC as ing agents. Based on X-ray diffraction (XRD), thermogravimetry-differential scanning …
The K supplied as K-feldspar was nearly unavailable to the plants, whereas nearly 60% of the K supplied as biotite and nepheline in a carbonatite, was recovered in harvested plants parts. The carbonate content of the rocks and tailings seemed to be more important for the availability of the K than
Lightweight ed ceramics were prepared using 55 wt.% vanadium-titanium magnetite tailings (VTMT) followed by sintering at 1130 °C. In the CaO-MgO-SiO2-Al2O3 ed ceramic quaternary system, the CaO and SiO2 components play an important role in adjusting material properties and controlling phase transition. In this work, the effect of …
There are also at least two other examples (feldspar tailings in North Carolina and coal refuse in Ohio) where these materials have been used on a local basis as fill and approved for highway construction. Table 9-6 is a summary of the known uses of mining and mineral processing wastes in embankments in these 16 different states. (1)
Commercial feldspar for glassmaking should contain 5–7% Na2O; 4–6% K2O; about 19% Al2O3 with maximum 0.08% Fe2O3 and a grainsize of 0.5–1.0 mm (Harben 1999). Potassium feldspar is preferred for ceramic manufacture; and should contain: 5–14% K 2O; a maximum 0.07% Fe2O3; and have a grainsize less than 75 µm. Economic Factors
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 economic analysis demonstrated that the flotation process in this study yields a profit of 50.96 USD per ton of treated tailings.
Large reserves of feldspar ore exist in the Aegean region of Turkey. The main colored impurities in these ores are iron- and titanium-bearing minerals such as anatase, rutile, sphene and ilmenite.
In feldspar processing, flotation beneficiation tailings that containing high ratio of titanium minerals emerge at a considerable amount as a result of beneficiation of feldspar reserves with high TiO 2 content due to required specifications by global feldspar market. Recovery of titanium minerals from these tailings which can be evaluated as …
The invention relates to a method for recycling single quartz and feldspar from gold flotation tailings. Harmful slurry and part of iron impurities are removed through a settlement desliming method; sodium carbonate is adopted as regulators and plays a role in restricting flotation of the quartz and the feldspar, YOA is adopted as a collecting agent …
The tailings dam is completely unprotected and its orange colour (clearly visible from satellite images) suggests a high concentration of arsenic sulphides (Alderton et al., 2014).
In order to recover about 35% feldspar and 35% quartz from a molybdenum tailings in Inner Mongolia, the flotation separation of quartz and feldspar by sodium oleate in the presence of magnesium ions was studied. Through the optimization of flotation conditions, at pH=11.0, Mg 2+ ion dosage of 300 g/t, and sodium oleate dosage of 900 …

Abstract. Feldspar is a valuable raw material in the manufacture of glass, ceramic, fillers, enamel frits, and welding electrodes. Feldspar is the single most abundant mineral in the earth crust and is generally associated with other silicate, titanium, and iron minerals. As a result, beneficiation of feldspar is necessary to obtain high-grade ...
At optimized conditions (45o oC, 30 min), about 39% of the Mg and 15% of the Ca in the tailings were extracted. While the Alternative ÅA Route proved successful in extracting phyllosilicate-bound magnesium, it was ineffective in extracting calcium from the tailings, which is mostly present in the form of plagioclase feldspar.
