Abstract

Mining from the city is one of the future directions for sustainable resource management. The separation of highly dispersed, low concentration valuable metals requires highly efficient extraction technology, where membrane extraction has shown significant advantages owing to its potentially high selectivity and low footprint. This review summarizes the recent progress in membrane extraction with respect to the development of membrane materials and the process configurations with special focus on preventing the loss of the organic extractant and/or degradation of the membrane materials. Prior research work was reviewed first on the development of various membrane materials for extending the ..
