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 …

Two pathways may therefore be possible for the extraction; (1) directly from the α-phase or (2) an initial α to β-phase conversion followed by a quick in situ lithium chloride formation due to the presence of calcium chloride (2α-spodumene → 2β-LiAlSi 2 O 6 + CaCl 2 → 2LiCl + 2SiO 2 + CaAl 2 Si 2 O 8 ). 3.3.

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 …

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. …

1. Introduction. Spodumene (LiAlSi 2 O 6) is a lithium aluminosilicate that acquired its name from the Greek word "spodumene" (burnt to ashes) due to its post-grinding ash-like grey colour.Spodumene is the most important lithium mineral to produce lithium compounds from hard rock lithium ores because of its significant Li 2 O content [, …

Spodumene. Spodumene is a lithium aluminum silicate (8.0% Li 2 O, 27.4% Al 2 O 3, 64.6%SiO 2) and is the world's most common commercially mined lithium ore mineral. Petalite, lepidolite and amblygonite are also mined in different parts of the world. Spodumene is a pegmatite mineral that has a glassy lustre and may be opaque; it is …

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. Visit gemdat for gemological information about Spodumene.

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.
