Life cycle impacts assessment of two gold extraction systems in
Purpose Gold mining has historically and significantly contributed to the Colombian economy. Gold extraction in Colombia is mainly done through two techniques: open-pit and alluvial mining. In this study, the environmental impacts of both these mining systems were analyzed using the life cycle assessment (LCA) framework, including Likewise, soil seed bank formation (Valois-Cuesta et al., 2017) and pioneer plant species (Valois-Cuesta & Martínez-Ruiz, 2017) during early revegetation of areas affected by gold mining have also been studied in Forest restoration after alluvial gold mining can
