Abstract: Spodumene tailing is the associated solid waste of extracting lithium from spodumene. With the increase in the global demand for lithium resources, its emissions increase yearly, which

Fine and coarse fractions of spodumene were obtained from a pegmatite ore and their flotation was investigated under different conditions. In particular, the optimum pH and collector dosage were studied. It was found that the best flotation performance occurs at pH 10 using 250 mg/L of sodium oleate. It was also observed that upon the addition of …

The δ 7 Li values of the spodumene (+5.58 to +6.57‰) are indicative of the incorporation of middle continental crustal components in their genesis. Change in the mineral assemblage from tourmaline-bearing in the intermediate zone to spodumene + tourmaline in the core zone of the spodumene-bearing pegmatite is consistent with …

The spodumene-containing fraction was conditioned at a little above 50% pulp density in a neutral pH using sodium oleate as collector. Spodumene in the conditioned material was floated at 30% pulp density and gangue minerals rejected to tailings. This led to 85% recovery and an upgraded concentrate of about 4.6% Li 2 O. …

A new collector prepared using decyloxy-propyl-amine (DPA) and α-bromododecanoic acid (α-BDDA) at a molar ratio of 1:1 increased the difference in the recovery of spodumene (82.14%) and feldspar (32.48%) significantly [53].The difference in recoveries of spodumene and feldspar was 27.47% while using DPA only, whereas the …

Heat-treatment of spodumene concentrate at 1323 K (1050 °C) for 30 min in a rotary kiln yielded a successful decrepitation. Particle size decreased from 2 cm to less than 425 µm for 80% of the initial mass. X-ray analysis of both fractions did not reveal the presence of α-spodumene or γ-spodumene. The coarse fraction was ground to less …

It focuses on the production of lithium compounds from spodumene minerals. Spodumene is one of the most critical minerals nowadays, due to its high lithium content and high rate of extraction. …

The pure mineral samples of spodumene and feldspar (albite) were obtained from the Jiajika Lithium Mine, Ganzi District of Sichuan province, China. The samples were hand-picked, crushed and ground in a laboratory porcelain mill, and −0.074 mm fractions were used in the experiments.Chemical composition analysis (Table 1) and X-ray …

In this study, the effects of Ca (II), Mg (II), Cu (II), and Fe (III) on the flotation separation of spodumene from feldspar and quartz were examined by single-mineral …

Conclusions. This contribution reported the phase transitions during calcination of a technical grade spodumene (7.6% Li 2 O) observed from in-situ experiments using hot-stage cathode-tube and synchrotron X-ray diffractometers. Smaller grain sizes and sample amorphicity enhance the formation of γ -spodumene, as …

Triphane Spodumene Emotional Healing Energy. Clear Spodumene is an excellent crystal for restoring energy, optimism and a sense of purpose. Passed in spirals over the body and the aura, it removes lingering sad memories, anxieties over past mistakes or failures, and helps dissolve negativity from others. [Eason, 374]

Spodumene can grow into enormous crystals. The largest single crystal found is a well-crystallized, 42 foot (12.8 meter) giant. Even the transparent gem forms can come in huge gemmy water clear crystals so large that need to be held with both hands. Spodumene is rarely seen on a matrix as it easily pops out of the host rocks. Because of their ...

Spodumene is worked as an ore of lithium, but it is most highly prized as a gem material - the varieties Kunzite (pink) and Hiddenite (green) are especially sought after. It is usually found as a constituent of lithium-rich pegmatites. It forms crystals to 12 meters in length.
