Metal purification ;Metal mixture;Etching
Use advice for data set Users of this data set should consider the environmental impact associated with the discharge of pollutants during the metal extraction process. When incorporating this data into Life Cycle Assessment studies, attention should be paid to the potential emissions and waste management practices related to the use of strong solvents. Additionally, users should assess the technological applicability of the process for the specific type of metal mixture being treated and evaluate the efficiency of the recovery method in the context of the metals' end-use.
Technical purpose of product or process This metal purification process is typically utilized for extracting metals from complex mixtures via hydrometallurgical recovery. The process involves the use of strong solvents and results in pollutant discharge. It is applicable, but not limited to, wet etching techniques in the metal finishing industry, where precision in metal composition is required.
