Lithium is considered to be the most important energy metal of the 21st century. Because of the development trend of global electrification, the consumption of lithium has increased significantly over the last decade, and it is foreseeable that its demand will continue to increase for a long time. Limited by the total amount of lithium on the market, lithium extraction from natural resources is still the first choice for the rapid development of emerging industries. This paper reviews the recent technological developments in the extraction of lithium from natural resources. Existing methods are summarized by the main resources, such as spodumene, lepidolite, and brine. The advantages and disadvantages of each method are compared. Finally, reasonable suggestions are proposed for the development of lithium extraction from natural resources based on the understanding of existing methods. This review provides a reference for the research, development, optimization, and industrial application of future processes.

Nitrogen-containing compounds (NCCs) in hightemperature coal tar have a negative impact on its utilization. This work aimed to prepare a series of Ce x Y adsorbents with superior capacity and selectivity by ion exchange, and further clarify the regeneration properties and adsorption mechanism. The adsorptive denitrogenation properties were evaluated at different temperatures using batch adsorption experiments in different model fuels. The implication of Ce loading on the adsorption properties has been studied. The results show that Ce 0.2 Y exhibits a remarkable performance in adsorption capacity. Ce 0.2 Y can reach 25.32 mg•N• g −1 absorption for quinoline and 23.78 mg•N•g −1 absorption for indole at 30 °C, which is much better than that of NaY. The effect of naphthalene on the adsorption of NCCs indicated that Ce 0.2 Y is much resistant to the influence of naphthalene. Furthermore, the regenerated adsorbents still retained better adsorption properties than NaY after five cycles. The adsorption mechanism for NCCs and naphthalene on Ce 0.2 Y was revealed by the IR spectra. By contrast, the interaction between Ce 0.2 Y and NCCs is stronger than the interaction between Ce 0.2 Y and naphthalene. The Ce 0.2 Y adsorbent preferentially adsorbed NCCs, which can be attributed to the introduction of Ce 4+ .
