Increasing demand for lithium-ion batteries has led to the development of several new lithium mineral projects around the globe. Some major mineral processing challenges these projects face are similarities in gangue and value mineral behaviour and poor selectivity in froth flotation.

Spodumene ores in North America typically fall between about 0.6% to about 1.2% Li2O. Ore grade and the rock matrix that the spodumene is associated with have a huge impact on mining …

Spodumene ore naturally occurs in the crystal structure of monoclinic alpha form (α-form). In order to extract lithium from the ore via the leaching process, however, the ore's crystal structure must be in the tetragonal beta form (β-form). ¹ This conversion is achieved through decrepitation, or the shattering of the crystal structure.

A 2021 study found that lithium concentration and production from brine can create about 11 tons of carbon dioxide per ton of lithium, while mining lithium from spodumene ore releases about 37 tons of CO 2 per ton of lithium produced. 5 . The social impacts of lithium mining depend on how mining companies behave and how …

Abstract: This literature review gives an overview of the lithium industry, including the lithium market, global resources, and processes of lithium compounds production. It focuses on …

The mechanism of anionic/cationic combination collector ST-8 for the efficient separation of spodumene and feldspar was investigated by flotation tests, surface tension measurements, zeta potential measurements and infrared spectroscopy analysis. The flotation results indicated that when the optimum molar ratio of sodium oleate and …

Spodumene, albite, quartz, K-feldspar, ... Lithium: Environmental Pollution and Health Effects. H. Aral, A. Vecchio-Sadus, in Encyclopedia of Environmental Health, 2011. Mining-Related Pollution. Mining and mineral-processing industries producing lithium minerals, metals, and salts contribute to the lithium burden in the environment. ...

In this study, we sampled surface waters (n = 47) near three Li-mica and one spodumene deposit to examine a potential public health risk resulting from the weathering of Li-minerals.

Lithium is in high demand: this is driven by current trends in e-mobility and results in increased global production and record prices for lithium ores and compounds. Pegmatite ores, in addition to brines, remain of particular interest because of their higher lithium content and lower geopolitical risks. In this work, we investigated lithium …

The process can be optimized if other high-value elements are found in spodumene deposits, residual lithium can be recycled during mining and processing, and energy savings can be achieved. This paper evaluates the sulfuric acid process for lithium extraction from spodumene from an operational, economic, and environmental …

1. Introduction. Natural spodumene occurs as α-phase, the low-temperature, monoclinic polymorph of LiAlSi 2 O 6 that resists dissolution by most chemical agents (Rosales et al., 2014).In lithium refineries, the thermal treatment of α-spodumene at temperatures above 1050 °C (typically around 1080 °C) transforms it into the more …

Health risks from exposure to lithium-bearing spodumene cleavage fragments are unknown. While asbestiform fibres can lead to fibrosis, mesothelioma and lung cancer, controversy remains whether …

However, this process generates huge quantities of waste residue and needs high-temperature pretreatment. The process can be optimized if other high-value …

Abstract. Among all of the lithium-bearing minerals, spodumene possesses the highest theoretical lithium abundance. Since the 1990s, Australia, with the world's …

The microwave temperature profiles of spodumene, and characterization results confirmed that α-spodumene started to transfer into γ- and β-spodumene at around 900 °C. AB - To utilize the advantages of microwave-assisted calcination over conventional heating, this work studied the effect of microwave power on phase transformation and ...

1. Introduction. Granitic pegmatites host various valuable industrial minerals (Glover et al., 2012).Among them, the aluminosilicate spodumene (LiAlSi 2 O 6) plays a major role as the world's current main lithium source (USGS, 2022).Moreover, spodumene-bearing pegmatites are found worldwide, giving them geostrategic advantages over other …

cation can be particularly challenging in spodumene flotation as this requires the selective depression of certain silicate minerals, but not spodumene [20. 23]. With specifications of < 1.0% Fe 2O 3 for battery-grade spodumene concentrates and < 0.17% Fe 2O 3 for ceramic or technical grade concentrates (ex. SC 7.2 > 7.2% Li

3.2.1. Effect of CaCl 2 /spodumene molar ratio . The effect of CaCl 2 /spodumene molar ratio (MR) on lithium recovery was studied in the range of 1.0 to 2.25, at 900 °C for 60 minutes residence time; the results are presented in Fig. 5. Lithium recovery increases with increasing molar ratio until it plateaus after MR = 2.0.

Still, Morrill, of Earthworks, says there's just not enough research about the effects of hard rock spodumene mining to say for sure that the mine wouldn't harm the environment. Since so many people in Maine depend on recreation and tourism for their livelihoods, she says, it makes the most sense to keep protective regulations in place.
