Comparative study of selective zinc leaching from EAFD using carboxylic agents

Revista Mexicana de Ingeniería Química, 2020
Recycling of industrial waste has become a process of highly positive impact on the environment, industry and human health. The management of the electric arc furnace dust (EAFD) is a necessary and interesting task due to the possible recovery of its elevated metallic content (Zn, Pb, Cu, etc.). This reduces the environmental pollution generated by the
