As ore quality declines in KGHM mines after continuous exploitation, it becomes increasingly relevant to extract as much economic value as possible from the mined ore while limiting the environmental impact. The recovery of cobalt from converter slag is a possible extraction route that can increase economic output at a limited environmental and logistic cost. Life cycle assessment (LCA) is used to assess the environmental impact of copper exploitation and to compare that impact with the estimated impact of cobalt extraction in the Lubin mine. In most impact categories, Co extraction would be responsible for less than 0.2% of the impact, while increasing economic output by 3.38%. Economic allocation shows that cobalt recovery is environmentally pertinent. |
