| Abstract Scope |
This study is focused on a rigorous analysis of the technoeconomics of supercritical fluid extraction (SCFE) technology applied to the recovery of rare earth elements (REEs) from neodymium iron boron magnets. REEs are in increasingly high demand; due to their limited supply, their recovery from electronic waste is highly promoted. SCFE process is recognized as a green alternative to hydro- and pyro-metallurgy to recover REEs from secondary resources. The technical feasibility of SCFE for recycling of REEs from end-of-life magnets has already been proven. Using a wide range of data sources including laboratory results, literature data, scaling models, scenario analysis, and sensitivity analysis, this study performs a sound economic analysis of the SCFE process at an industrial scale. The findings demonstrate the SCFE of REEs can be economically viable under certain circumstances, with the efficiency of extracting dysprosium and neodymium and their oxide prices being the main drivers of profitability. |
