Two alternative process routes for recovering pure indium from waste liquid crystal display panels
Recovering indium from liquid crystal display (LCD) screen waste is important from a sustainability point of view for several reasons: the environmentally hazardous metals are not landfilled, the recovery process involves ...
Solvent extraction fractionation of Li-ion battery leachate containing Li, Ni, and Co
In this research, the separation of Li, Ni, and Co by solvent extraction was studied from synthetic Li-ion battery waste leachate. The purpose was to propose a process for producing all the metals with over 99.5% purities, ...
Removal of calcium and magnesium from lithium brine concentrate via continuous counter-current solvent extraction
In this research project, a process for purifying Li brine concentrate with a typical composition of Li 30 g/L, Ca 1.36 g/L, Mg 0.049 g/L via solvent extraction was studied. The goal was to remove Ca to below 20 mg/L and ...
