“…The most efficient for iron(III) transport using PEHFSD is Primene JMT based IL. Recently Primene JMT has been used for preparation Primene JMT-Cyanex 272 ionic liquid for liquid-liquid extraction and separation of Co(II) and Ni(II) (more than 99 % Co and about 10 % Ni in the extract) from neutral chloride solutions [115] . The best separation of Co(II) from Ni(II) has been obtained for the organic phase containing 10 % Cyanex 272+10 % JMT in aliphatic hydrocarbon Exxsol D100.…”

After near 70 years of practical usage, solvent extraction is a perfectly mastered technique of separation, widely used on an industrial scale for the separation of metals mainly from raw materials. However, currently, in the era of depleting natural resources and increasingly less accessible deposits, environmental restrictions, etc., an increasing interest, both from social and economical constrains, is being directed at the extraction of metals from the secondary sources (such as batteries, electronic scrap). In many cases, solvent extraction, due to its operational characteristics, can be considered as the Best Available Technology for the purpose of separating multielemental metal solutions. This paper provides a brief overview of past achievements and present scenario of solvent extraction investigations and developments, describing some recently commissioned solvent extraction plants, whereas the Skorpion Zinc plant (Namibia) for zinc extraction from raw materials and caesium removal from radioactive High Level Wastes (HLWs) are told over in detail as case studies. The paper also presents some proposals for the use of liquid-liquid extraction to separate metal ions from secondary sources (e.g. cobalt from industrial waste streams). The review highlights the emerging use of ionic liquids as new extractants for metals, providing an insight into this exciting research field. Despite its detractors, solvent extraction has entered in force into XXI century as a leading separation technology for metals.

Tendencias recientes en la extracción de metales ResumenDespués de casi 70 años de uso práctico, la extracción líquido-líquido o extracción con disolventes es una técnica de separación muy evolucionada, utilizándose a escala industrial en el beneficio de metales obtenidos de diversas materias primas. Sin embargo, con el agotamiento de los recursos naturales y el aumento de depósitos minerales de más difícil acceso, restricciones medio ambientales, etc., ha aumentado el interés, tanto desde el punto de vista económico como social, en la recuperación de los metales contenidos en materiales secundarios (baterías, chatarras electrónicas). En muchos casos, la extracción líquido-líquido y debido a sus características operacionales, se considera como la mejor tecnología disponible respecto a la separación de disoluciones metálicas multielementales. Este trabajo considera algunos de estos anteriores estudios y presenta la situación actual de la tecnología en cuanto a investigaciones y desarrollos, describiendo algunas de las más recientes plantas industriales en funcionamiento, detallando la planta Skorpion (Namibia) para la obtención de zinc, así como investigaciones encaminadas a la eliminación de cesio de efluentes radioactivos. También se presentan algunas de las propuestas encaminadas a la separación-recuperación de metales de materiales secundarios (por ejemplo, cobalto). Por último, se describe el uso emergente de los iones líq...

“…Due to the favorable properties like low vapour pressure, high liquidus range, large electrical potential window, high thermal and radiation stability, high degree of solubility for organic, inorganic and polymeric substance, room temperature ionic liquid was considered as potential 'green' alternatives to volatile organic compounds in various fields like synthesis (Ziyauddin et al, 2014), catalysis (OlivierBourbigou et al, 2010), electrochemistry (Liu et al, 2010), separation science (Han and Row, 2010;Coll et al, 2012;Castillo et al, 2014;Swain et al, 2016) and even drug delivery (Shamshina et al, 2013). Though, the 'greenness' of ionic liquid is nowadays controversial and matter of discussion, still the ionic liquid based research is the centre of attraction because of its tunable properties and unconventional chemistry (Suresh and Suresh and Sandhu, 2011).…”

“…Currently, this operation predominantly uses the commercial extractant Cyanex 272 (bis (2,4,4-trimethylpentyl) phosphinic acid) (Coll et al, 2012;Flett, 2005;Mantuano et al, 2006), as this reagent presents a high selectivity for the separation of cobalt, copper, and manganese, thus maintaining nickel in solution (Devi et al, 1998). However, the presence of unextracted alkaline earth metals, such as calcium or magnesium, which remains with nickel in the liquor may seriously interfere in the successful operation of the electrolytic process.…”
