Red Mud as a Secondary Source of Scarce Metals - Recovery using Red Microalgae
Náhlík V., Čížková M., Singh A., Bišová K., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic:
Environmental biotechnology and bioenergy
Red mud is a by-product of the production of alumina from bauxite ore. Less than 2% of the red mud produced is currently being reused. The red mud contains a number of residual elements, some at a considerable concentration. The red microalga Galdieria sulphuraria was used to test the accumulation...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
