Flue Dust - an overview ScienceDirect Topics

Bioleaching of Smelter Slags and Flue Dust. Flue dusts from copper smelters contain 30–35% Cu. Using a mixed culture of A. ferrooxidans and A. thiooxidans, 87% of copper could be recovered from the flue dust. Using stirred tank bioreactors, copper recovery could be further increased to 91%.
