“…This allowed the calculation of the mass and energy balance of the process, which was adapted into a life cycle inventory (LCI). Life cycle assessment is a standardized framework for assessing the environmental impacts of a product or a process (ISO 14040 2006a(ISO 14040 , 2006b, and a similar process model-based approach has been validated in several earlier metallurgical studies (Abadías Llamas et al 2019;Elomaa et al 2020aElomaa et al , 2020bFernandes, Abadías Llamas and Reuter 2020;Pell et al 2019;Reuter 1998). The life cycle impact assessment (LCIA) was conducted using GaBi software (sphera 2020).…”

A simulation-based life cycle assessment was conducted to compare the impacts of different cyanide-free chloride processing routes for refractory ores to determine whether one-stage leaching of gold from the ores could be advantageous over chloride leaching after conventional pressure oxidation from an environmental perspective. It was shown that both leaching conditions and the refractoriness of the ore strongly affect the environmental impacts of the process. The global warming potential in the direct leaching route was determined to vary between 7.7-17.0 t CO 2 -eq for 1 kg gold/Au. Prerequisites for the sustainable application of the direct leaching process are suggested.
