In the complex production required to transform spodumene concentrate into lithium compounds such as lithium carbonate or lithium hydroxide, calcination plays a key role in not one, but two parts of the process, making it an essential technique in efforts to exploit this increasingly important lithium ore.

Keliber’s spodumene beneficiation process was identified as a very promising monitoring application for time-gated Raman spectroscopy. Real-time slurry monitoring at GTK Mintec. The measurements were carried out at GTK Mintec facilities using two MonitOre instruments equipped with 532nm pulsed lasers.

The spodumene behaves like micaceous and clay minerals in heavy media separation and thus its separation is affected. Thirdly, spodumene is reported to break into acicular particles that tend to float with gangue minerals (Munson and Clarke, 1955). These factors contribute to the poor recoveries obtained in spodumene beneficiation using DMS.

The beneficiation process can be defined as a treatment process of ore which results in a more concentrated form of the product. It is often used in the preparation of iron ore for smelting. This is an essential process as it helps improve the yield from a deposit of ore, thereby increasing the potential profits that can be obtained from the

During the thermal process, there is a dislocation of Al 3+ in the α-spodumene leading to aβ-spodumene crystal structure with a comparably larger crystal volume. This increases the mobility of lithium atoms which then become easily accessible to aqueous lixiviant solutions [ 4 , 10 , 11 ].

β-spodumene. The α-spodumene is virtually refractory to hot acids. As a result of the phase transformation, the spodumene crystal structure expands by about 30% and becomes amenable to hot sulphuric acid attack. Due to this expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/

The spodumene moves to a dryer and kiln that operate at about 1,000°C. This process converts the mineral into an easy-to-extract form using acid. This stage in the process also has the potential to release chemicals in the environment, some of which can be attributed to the fuel quality, calciner design, and emission abatement steps.
