“…where [Co]aq initial is the initial cobalt concentration before extraction, [Co]aq is the final silver concentration after extraction, while A and O are the volumes of aqueous and organic phases, respectively. Aiming for industrial application, the number of stages required for a continuous process was computed by using the McCabe-Thiele method [21]. Each step is described below.…”

“…While solvent extraction has industrial applications in the recovery and purification of metals from lixiviation liquors and residues of materials [21], few works have proposed solvent extraction to recover cobalt [22,23], copper [24], and other metals of spent batteries [25]. This work focused on the recovery of cobalt by solvent extraction, measuring the effect of parameters such as time, pH, and concentration of the extractant.…”

The aim of this paper was to propose and test a continuous cobalt recovery process from waste mobile phone batteries. The procedure started with dismantling, crushing, and classifying the materials. A study on leaching with sulfuric acid and hydrogen peroxide was carried out with subsequent selective separation of cobalt by means of liquid–liquid extraction. The best extraction conditions were determined based on a sequence of experiments that consisted of selecting the best extractant for cobalt, then assessing the impact of extractant concentration, pH, and contact time on the extraction yield. With these conditions, an extraction isotherm was obtained and correlated with a mathematical model to define the number of extraction stages for a countercurrent process using the McCabe–Thiele method. Then, a similar study was done for stripping conditions and, as a last step, cobalt electroplating was performed. The proposed process offers a solution for the treatment of these batteries, avoiding potential problems of contamination and risk for living beings, as well as offering an opportunity to recover valuable metal.

“…The separation of bio-active compounds of interest in different industries such as food and pharmaceutical usually employs the use of large amounts of solvents (water, n-hexane, ethanol, chloroform, methanol, petroleum ether, etc.). Over the last decades researchers have concentrated lots of efforts on the design of efficient and more sustainable methods of extraction which are less detrimental to the environment [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Extractions have moved from the conventional solvent and mechanical extractions to improved nonconventional techniques such as Supercritical Fluid Extraction (SFE) and extraction assisted by ultrasound (UAE) and microwaves(MAE) [16][17][18].Grinding is a very essential operation in the preparation of materials for oil extraction irrespective of the method that follows because when carefully controlled it can lead to the achievement of high oil yields and positively influences downstream operations [19].…”

Most seed oils are edible while some are used generally as raw material for soap production, chocolate, margarine, and recently in biodiesel formulations as potential candidates capable of replacing fossil fuels which are costly and destructive to the environment. Oilseeds are a green and major reservoir which when properly exploited can be used sustainably for the production of chemicals at both the laboratory and industrial scales. Oil extraction is one of the most critical steps in seed oil processing because it determines the quality and quantity of oil extracted. Optimization of the extraction conditions for each extraction method enhances yield and quality meanwhile a carefully chosen optimization process equally has the potential of saving time and heat requirements with an associated consequence on cost reduction of the entire process. In this review, the techniques used to optimize oil extraction from plant materials which can be consulted by stakeholders in the field are brought to focus and the merits and demerits of these methods highlighted. Additionally, different types of optimization techniques used for various processes including modeling and the software employed in the optimization processes are discussed. Finally, the quality of the oil as affected by the methods of extraction and the optimization process used are also presented.

“…However, this form of vanadium is non-extractable by tertiary amines (Floh (Miss), B., Abrao, A., Calmon Costa, E., 1971). That is why the reoxidation according to equation (10) of iron (II) naturally present in the environment (from the gangue) by the NaClO3 made it possible to oxidize the vanadium. The oxidation of V(IV) to V(V) has allowed to increase the extraction percentage of vanadium from 0% to 15%.…”

This study focuses on the liquid-liquid extraction of uranium by anionic extractants of Alamine 336 and Aliquat 336. The objective of this study is to determine the parameters allowing the optimization of the extraction percentage of uranium, and other metals such as molybdenum, zirconium and vanadium. The extraction kinetics of uranium is achieved in 2 minutes. Sulfuric acid solutions are the media per excellence when using Alamine 336 as extractant. However,with Aliquat 336, it is orthophosphoric acid. Uranium is extracted at 99% in a single contact from the ratio: organic phase over aqueous phase (O/A) equals 1. The extraction of uranium with Alamine 336 depends on the initial pH of the aqueous phase as well as the Alamine 336 concentration. Alamine 336 tends to release the uranium and the extracted zirconium until the 3 rd contact to the benefit of the molybdenum due to the natural occurrence of 𝐶𝑙−,𝑁𝑂3 − and 𝐹 − ions in the uranium-bearing solutions which have the tendency of breaking the anion complexes. Vanadium, which is not extracted by Alamine 336 and Aliquat 336, can, in the hydrodynamic conditions of this work, be extracted by increasing the redox potential to 800 mV and pH ≥ 1.
