Separation of Copper from Chalcopyrite – Ammoniacal Leach Liquor Containing Copper, Zinc, and Magnesium by Supported Liquid Membrane
A low grade chalcopyrite ore was leached with H2O2/(NH4)2SO4 and the leach liquor contained 42.96 mol m copper, 3.52 mol m zinc and 11.23 mol m magnesium. From this leach liquor separation of copper was carried out with supported liquid membrane using LIX84I as mobile carrier. Celgard 2400, a microporous polypropylene film was used as the solid support for the liquid membrane. The effect of pH ...
متن کاملEffect of Complexation Reaction Constant on the Separation of Propylene/Propane by Supported Liquid Membrane
Traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. Facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. To design a membrane process for olefin-paraffin separation, equilibriu...
متن کاملSupported Liquid Membrane in Metal Ion Separation: An Overview
Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...
متن کاملIn-situ preconcentration, and electrochemical sensing of zinc(II) and copper(II) based on ionic liquid mediated hollow fiber-modified pencil graphite electrode using response surface methodology
A single-use electrochemical sensor using ionic liquid mediated hollow fiber-graphite working electrode was fabricated for the first time. The screening tool was developed by coupling this electrode with differential pulse voltammetry (DPV) for in-situ pre-concentration and determination of Zn(II) and Cu(II). In our plot, porous polypropylene hollow fiber membrane was divided into pieces of 2 c...
متن کاملMathematical Modeling and Numerical Simulation of CO2 Removal by Using Hollow Fiber Membrane Contactors
Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations of the model are solved via the finite...
