Spodumene concentration is a complex process involving dense media separation (DMS), flotation, and magnetic separation. DMS typically processes coarse material (>850 μm) and can produce a coarse final spodumene concentrate while often also acting as an upstream upgrading stage for the flotation feed.

The coarse fraction was ground to less …
In coming years, global lithium production is expected to increase as the result of widespread electric vehicle adoption. To meet the expected increase in demand, lithium must be sourced from both brine and hard-rock deposits. Heavy liquid separation (HLS) and dense media separation (DMS) tests were conducted on the pegmatites from …

Lastly, the spodumene price per carat for rough specimens at wholesale is $0.01-$5 per carat. Spodumene Care and Maintenance. Spodumene is relatively hard, but its cleavage and parting planes mean it can break easily. Therefore, caring for the gem carefully is key. We recommend spodumene jewelry like pendants or earrings over rings and bracelets.

The thermal behavior of spodumene and the concentration of its polymorphs were studied by heat treatments in the range of 900 to 1050 °C. All three polymorphs of the mineral (α, γ and β) were identified. Full transformation of the α-phase was achieved at 975 °C and 1000 °C after 240 and 60 min treatments, respectively.
Fig. 4 (b) shows that, for the spodumene particles of −0.074 + 0.0385 mm, the effect of the two pretreatment methods on the flotation performance of spodumene particles is similar to that of −0.15 + 0.074 mm particles. Only 5 min of ultrasonic pretreatment can increase the subsequent flotation recovery to the effect of 20 min of traditional ...

This suggests that, the extraction of lithium chloride is directly from the α-phase. A possible transformation of α-spodumene into β-spodumene followed by a fast synthesis of lithium chloride from β-spodumene (2α-spodumene → 2β-LiAlSi 2 O 6 + CaCl 2 → 2LiCl + 2SiO 2 + CaAl 2 Si 2 O 8) may also occur.
