metal extraction is implemented by hydrometallurgical recovery with strong solvents and pollutant discharge. When using this data set, users should account for the environmental impact of strong solvent use and pollutant discharge that occurs during the leaching process. It is important to include these impacts in the Life Cycle Assessment to ensure a comprehensive evaluation of the process. Additionally, users should consider the technological applicability based on the intended recovery of certain metals and the purity levels achieved. The data should not be applied to processes that do not employ hydrometallurgical methods or for materials that do not react with nitric acid. Consideration should also be given to the geographic and technological relevance of the data to the specific context in which it is applied.
