The northwestern part of Jiangxi Province is an important Li–Nb–Ta–Be metallogenic region in China where the Yichun, Xiushui, and other rare-metal deposits are found (Wang et al., 2018, Yin et al., 1995).The Yifeng deposit is also located in this region, near Yifeng County, including Nanmukeng, Baishuidong and Tong'an from north to south,.
The process can be voltage-controlled to minimize Na and Mg ions participating in the Li removal process. When the electrode in A is full, a new or recycled Fe III PO 4 is replaced and the process continues. As a result, Li will be continuously removed from the brine (A) and Li will be gradually concentrated in the pure electrolyte (B).
Hardrock mining is another method that involves extracting and refining lithium-bearing minerals such as spodumene. This process is energy-intensive and can have adverse environmental impacts. In recent years, a new innovative process called Direct Lithium Extraction (DLE) has emerged as a promising alternative. DLE technologies aim to extract ...

The effect of metal ions present in water on mineral flotation has been well documented in the literature (Fuerstenau et al., 1985, Fornasiero and Ralston, 2005, Boujounoui et al., 2015, Bulut and Yenial, 2016).These metal ions can activate or depress mineral flotation; for example, sphalerite flotation can be activated/enhanced with copper ions addition but …
Process mining is a promising approach that turns event logs into valuable insights about processes. One domain amenable to process mining is healthcare, where an enormous amount of data is ...
This study explored the power of fine-tuned large language models (LLMs) on five intricate chemical text mining tasks: compound entity recognition, reaction role labelling, metal–organic framework (MOF) synthesis information extraction, nuclear magnetic resonance spectroscopy (NMR) data extraction, and the conversion of reaction paragraphs to ...
Dear Colleagues, Despite several developments over the past decades, the mineral extraction sector is facing new challenges associated with environmental (bio)geochemistry in the mining environment, from the prediction of water quality as early as possible in the life cycle of a mine all the way through mine site reclamation/closure, water …

Process mineralogy plays a key role in defining the properties of ores, identifying key opportunities, and ascertaining potential challenges associated with the extraction of lithium.
Seawater contains significantly larger quantities of lithium than is found on land, thereby providing an almost unlimited resource of lithium for meeting the rapid growth in demand for lithium batteries. However, lithium extraction from seawater is exceptionally challenging because of its low concentration (
The clean energy transition requires a considerable amount of different minerals, and lithium is one of the most critical elements owing to its use in Lithium-ion batteries for various applications.
Solar energy is a clean and sustainable natural energy, and solar-to-chemical (STC) energy conversion has been extensively researched in the past few decades [1], [2], [3].A practical approach to converting solar energy into chemical energy is the photoelectrochemical (PEC) process, which involves the use of light absorption components and highly active …
The Weilasituo Cu-Zn deposit and Bairendaba Pb-Zn-Ag deposit were discovered in this mining area at the beginning of this century. A new Sn-polymetallic deposit was discovered and explored about 2 km northwest of the Weilasituo Cu-Zn deposit in 2013–2017, and Li-Rb mineralization was recently discovered in the cryptoexplosive breccia pipe of the Sn …
