Bu safsızlıklar renk verir nitelikte olduklarından feldspat cevheri kalitesinde düşüşe yol açmaktadırlar. Türkiye feldspat cevherleri genelinde yapılan mineralojik araştırmalar rutilin ve nadiren titanatın asıl titanyum mineralleri olduğunu, demir içeriğinin ise esasen mika minerallerinden kaynaklandığını işaret etmektedir.
The contact angle results for spodumene, feldspar, and quartz treated in 1500 mg/L NaOH solution, in the presence and absence of NaOL (6.5 × 10 −4 mol/L), are shown in Table 1.In the absence of NaOL, the contact angles at the surface of spodumene, feldspar, and quartz without NaOH pretreatment (ground in DI water) are 15.5°, 13.5° …

The binary mixed mineral flotation experiment of quartz and spodumene was carried out to verify the separation effect, and the results are shown in Table 2. From Table 2, spodumene and quartz can be separated using pectin as depressant at pH 11, and a concentrate with a Li 2 O grade of 6.78% and a recovery of 65.79% is achieved. While …
Pure natural samples, further purified in laboratory, and commercial reagents were employed. The minerals were characterized by X-ray diffraction technique. Selectivity between spodumene and quartz was achieved through modification with corn starch and between lepidolite and quartz through pH control in the acidic range. (ERA citation …

Spodumene typically contains about 1% iron oxide, giving the mineral a light green color. Muscovite contains 1–2 wt% FeO and a trace of sodium (0.2–0.6 wt% Na 2 O). A Mn-bearing fluorapatite (altered to low-F and low-Mn apatite) and triphylite (altered to fairfieldite) occur within the pegmatite fabric and appear to be primary phosphate ...
The Peg Claims pegmatites are located southwest of Rockland in the towns of Warren and Cushing, Knox County, Maine. These pegmatites are representative of a group of zoned, granitic, lithium-bearing pegmatites in which spodumene is present nearly from wall to wall. The pegmatites are discordant, steeply dipping, tabular bodies in the Penobscot quartz …

According to the literature, spodumene ores generally contain approximately 20% spodumene, 44% feldspar, and 31% quartz (Rai et al., 2011, Xu et al., 2016). 2.3 . …
Spodumene (LiAlSi 2 O 6 ) occurs in coarse-grained pegmatite deposits and co-exists with quartz, feldspar, and micas [10]. Despite the occurrence of L > 5 µm and D ≤ 1 µm as counting criteria ...
The Moblan pegmatite belongs to the albite–spodumene subtype of the rare-element granitic pegmatites enriched in Li, Cs, and Ta (LCT) (Černý and Ercit, 2005).The Main Sill consists of three principal zones from the contact with gabbro to the center: 1) a narrow border zone, usually less than one m in width, rich in albite with quartz, minor …
The mineralization occurred in a quartz-microcline-spodumene pegmatite, but good crystallized specimens of spodumene are actually quite rare to find on the market. This particular thumbnail is honestly the finest crystallized example of spodumene from this locality that I've ever had. I've seen larger examples (the Smithsonian has a 15 cm ...
The recovery of spodumene, feldspar and quartz under this condition was 5.39%, 89.31% and 91.7% respectively, which indicated that PPPDA had the potential to be used as a collector in reverse flotation of crude concentrate. The adsorption mechanism was investigated systematically by zeta potential, FT-IR, AFM, and adsorption amount …

In pegmatites containing abundant petalite and spodumene, such as those from the Barroso–Alvão (BA) aplite-pegmatite field, calibrating a portable laser-induced breakdown spectroscopy (pLIBS) equipment to identify and analyze these minerals may be challenging. Forty-nine samples of spodumene, petalite and spodumene + quartz were …
The first assemblage occurs along the cleavage planes of spodumene, whereas the second forms as the result of spodumene breakdown. Fine mica grains surrounded the cookeite aggregates in the second assemblage only. Precipitations of cookeite and quartz in open pore spaces and parallel packets of cookeite and kaolinite were identified by TEM.
