In this work, a new extraction method termed aerosol phase extraction has been developed for the first time. The new method was based on the nebulisation of the sample onto the extracting solution to maximize the contact surface. The influential parameters are: agitation time, chelating agent concentration and inorganic acid concentration. The method has been applied to the extraction of molybd...

Solvent extraction of copper in hollow-fiber membrane contactors was investigated in this study. Extraction of copper is carried out conventionally using mixer-settlers. These contactors have some disadvantages such as consumption of high energy, dispersion of two phases and high operating costs. Membrane contactors can obviate the need for conventional contactors. The most favorable module use...

The performance requirements of modern lithium-ion batteries (LIBs) necessitate the use a number scarce and strategically sensitive metals such as lithium cobalt. Recycling end-of-life LIBs reduces demand on primary sources these helps reduce environmental impact LIB waste. Citric acid has proven to be an effective environmentally friendly sustainable lixiviant; however, formation metal citrate...

Rare earths are critical elements in our modern societies and the ever-increasing demand raises fears of supply risks coming years. This work dealt with feasibility extracting rare earth (REEs) from an industrial waste product exploitation phosphate ores “Djebel Onk” Tébessa eastern region Algeria. The solid residue was first leached at room temperature three different inorganic acids (HNO3, H2...
