2 Material and Methods 2.1 Materials. LIB black mass samples were provided by RMF (Freiberg, Germany). The recycling process depicted in Fig. 1 had previously been developed and optimized for obtaining Li 2 CO 3 by the COOL-process 2.In the present work, the starting material is the solid residue obtained after the COOL process, which is after leaching …
The recycling of valuable metals from spent lithium-ion batteries (LIBs) has great significance for environmental protection and resource conservation. In this paper, a low-temperature clean chlorination roasting-water leaching process was proposed to simultaneously extract Li, Ni, Co and Mn from ca …
Natural Products from medicinal plants either as pure or as a standardized extracts provide unlimited opportunities for new drugs because of the unmatched availability of chemical constituents.
Process schematic for multistage liquid-liquid extraction. Determining number of stages when (1) feed rate; (2) feed composition; (3) incoming solvent rate; (4) incoming solvent composition; …
Extraction is a term that is used to define the transfer of any compound from its original state such as solid or liquid to another phase. It can be understood as the separation of the compound from a matrix [1], [2].It can be explained by various types such as liquid–liquid extraction, solid-phase extraction, acid-base extraction, ultrasound-assisted extraction, heat …
The extraction of lithium-rich brine can have significant environmental and social implications, underscoring the imperative need for responsible practices. Water usage in the extraction process can be intensive, potentially depleting local water resources and affecting communities and ecosystems reliant on these aquifers.
Liquid-liquid extraction (LLE), often referred to as solvent extract ion, is a common process for the selective extraction, separation, purification and concentration of a wide range of metals ...
Solvent extraction also termed as 'liquid-liquid extraction' or 'chemical extraction', is another viable process for Li recovery from brine due to its low cost and high product yield. The idea is to utilize some organic solvents that are capable of dissolving a significant amount of Li chloride with good selectivity towards the unwanted ...

Biotechnology is one of the emerging fields that can add new and better application in a wide range of sectors like health care, service sector, agriculture, and processing industry to name some.
The main discussion is categorized into three perspectives such as the evolution from the conventional to the advanced LIBs (e.g., Li-rich transition metal oxide and Ni-rich transition metal oxide batteries), to the state-of-the-art LIBs (e.g., Li-air, Li-sulfur batteries, org. electrode batteries, solid-state batteries, and Li-CO2 batteries ...
The entire PEF extraction process took less than 1 s and much less than the other tested methods . In a study of antioxidants extracted from Norway spruce bark, Bouras found that much higher phenolic content (eight times) and ... Xs Li, Bq Jiang, Jl Mao. Study on extraction separation and pharmacodynamics of effective components in Kuqingcha ...
Chlorella vulgaris, like a wide range of other microalgae, are able to grow mixotrophically. This maximizes its growth and production of polysaccharides (PS). The extracted polysaccharides have a ...
How to perform an extraction. For simplicity's sake, we will assume that the product is a neutral compound. Make sure the stopcock is closed. Add a small amount of …
Under these conditions, the extraction rate of Li 2 O reached 89–92%, Al 2 O 3 –79–93%. The alkalinity and caustic module of the aluminate solution are interdependent: using the more concentrated alkaline solutions, high extraction of Li 2 O, and Al 2 O 3 can be achieved at lower values of the α k.
In contrast to solvent extraction and ion-exchange resins, which use <1 m 3 of fresh water per ton of Li 2 CO 3, ion sieve sorbents typically require significantly more water, often exceeding 1000 m 3 per ton of Li 2 CO 3 [80]. Solvent extraction has shown adequate efficiency and lithium recovery, with many studies reporting over 90 % recovery ...
Alginate is an attractive marine resource-based biopolymer, which has been widely used in pharmaceutical, food and textile industries. This paper reviewed the latest development of the conventional and alternative processes …
In recent years, the supercritical CO2 extraction method has gained attention due to its use of environmentally friendly, non-toxic solvents, ability to operate at lower temperatures that do not ...
The optimal conditions for polyphenol extraction from potato peel using conventional solvent extraction (CSE) and ultrasound-assisted extraction (UAE) methods were predicted to estimate the ...
Brine is a rich and a sustainable source of Li. Low Li concentration in seawater brine pose challenges. Desalination brine is an attractive Li source due to higher …
In this work, a novel process using ferric salt solutions was developed for the green and efficient extraction of lithium in Li-rich clay sample obtained from carbonate-hosted clay-type lithium resources. In comparison to acid leaching, the ferric salt solution leaching process has the advantages of lower acidity with more neutral residues.
A fine extraction process should isolate lignin with high yield and high purity, and retain β-O-4 ether bonds, which would be advantageous for successive valorization routes [20]. Lignin extraction process is complicated, as it is covalently linked to hemicelluloses forming lignin-carbohydrate complexes [18].
Natural medicines were the only option for the prevention and treatment of human diseases for thousands of years. Natural products are important sources for drug development. The amounts of bioactive natural products in natural medicines are always fairly low. Today, it is very crucial to develop effective and selective methods for the extraction and isolation of those …

NE TLDOE PATENT STATUS: TECHBRIEF(19)-023, DECEMBER 2019 APPLICATIONS: • Extraction of Li and REEs from natural brines or other sources such as sea water and oil- and gas-produced water. • Potential extraction and recovery of dissolved elements from industrial liquid waste. • Development of a domestic supply of Li and REEs.
A novel process for the extraction of Li from lepidolite using HCl can decrease the dependence on costly neutralizing reagents and increase the overall yield of alkali metals extracted from lepidolite (Eqs. 7–9 in Table 12). About 95.7% of Li was extracted using 6.21 mol/L HCl at a L/S of 3, and digestion temperature of 108 °C for 8 h.
