Lithium is one of the critical elements required for clean energy technology to achieve a carbon-neutral target. In this study, the beneficiation of a low-grade spodumene ore (0.3–0.6% Li 2 O) from Eastern Kazakhstan is investigated by dense medium separation (DMS) and froth flotation to obtain lithium concentrate. The main gangue …
Lithium is found in minerals such as spodumene, amblygonite, zinnwaldite, petalite, and lepidolite . In order to meet the increasing demand for lithium, there is a requirement to optimize the beneficiation of lithium ores [2, 3]. Froth flotation is an important process for the recovery of lithium minerals from their ores .
Abstract. An increasing demand for lithium-ion batteries is driving the development of new lithium mineral projects. Spodumene, a major lithium-bearing mineral found in pegmatite deposits, is often recovered by froth flotation. The primary collectors in spodumene flotation are fatty acids which are known for their poor selectivity.
Flotation is the most widely used beneficiation method for lithium minerals, including spodumene. While sodium oleate is often used as a collector in spodumene flotation, recent studies have suggested new collector mixtures for this purpose [ 4, 5 ].
Depletion of high-grade resources has necessitated the use of low-grade fines, which contain good amount of mineral values and also liberate in finer sizes. Froth flotation, a physico-chemical surface-based …

The number of published studies related to the optimization of lithium extraction from low-grade ores has increased as the demand for lithium has grown. However, no study related to the kinetics of the concentration stage of lithium-containing minerals by froth flotation has yet been reported. To establish a factorial design of …
Pollucite mineral is a carrier of caesium and is found along with lithium, feldspar, mica, and the other silicates. Pollucite is an aluminosilicate mineral with variable composition and color. In various research work, two beneficiation methods were developed including direct pollucite flotation and reverse associated mineral flotation.

During standard processing lithium mineral concentration follows the simplified chart of Fig. 1 (Garret, 2004). The enrichment involves crushing and grinding steps in order to liberate the lithium minerals and adjust the grain size distribution for the subsequent separation steps, e.g. flotation or gravity separation.
open access. Flotation is a complex process that occurs in solid–liquid-gas multiphase systems, and its main factors include the minerals, separation medium, as well as various flotation reagents. The study of mineral properties and interactions with other components such as reagents and water lays the basic theoretical foundation for flotation.

The comminution of spent lithium-ion batteries (LIBs) produces a powder containing the active cell components, commonly referred to as "black mass." Recently, froth flotation has been proposed to treat the fine fraction of black mass (<100 µm) as a method to separate anodic graphite particles from cathodic lithium metal oxides (LMOs). So far, pyrolysis …
