Technical note membrane transport of copper with lix-860 from acid leach waste solutions
(Elsevier Ltd, 1997)
A membrane transport process is described. The process was developed for use in the recovery of copper from nitric acid leach residual solutions. The flux and the extraction extent of copper with 5-dodecylsalicylaldoxime ...

Recovery of copper from leaching residual solutions by means of a hollow-fiber membrane extractor
(Elsevier Ltd, 1996)
A process of recovery of copper from acid leach residual solution with 5-dodecylsalicylaldoxime dissolved in n-hexane was carried out at 30°C in a countercurrent tubular membrane extractor using a hollow fiber as solid ...
Extractability of copper and application of diffusive gradients in thin films: metal availability in contaminated soil by biosolids
(2013)
O objetivo deste estudo foi utilizar a técnica de difusão em filmes finos por gradiente de concentração (DGT) para a avaliação da disponibilidade de cobre em solos com elevados níveis do metal, que foi alterado com ...
