Biomining - recovery of high-tech critical metals

BUTU A., RODINO S., (Corresponding) BUTU M.

Topic:

Circular economy and industrial symbiosis

Critical metals were defined as those metals essential for high-tech, medical and defense industry but with low availability due to uneven geographical distribution, thus resulting a high price volatility. The challenge of the future is to assure a stable supply of critical materials and implicitly...Read more

Bioleaching of valuable elements from red mud using autochthonous biomass

(Corresponding) Cozzolino A., Cappai G., Cara S., Milia S., Carucci A.

Topic:

Circular economy and industrial symbiosis

Red mud (RM) is the main residue produced by the alkaline extraction of aluminum from bauxite, and it contains valuable metals (e.g., iron, aluminum, titanium, silicon). Aim of this research was to investigate the biologically induced leaching of valuable elements from RM using autochthonous...Read more
