Factors and challenges in the recovery of niobium and

The conventional extraction of Nb/Ta from mineral sources involves the use of HF or HF/H 2 SO 4 acids under harsh/hazardous conditions of toxic, concentrated and corrosive media with several complicated beneficiation and pyro-hydrometallurgical extraction steps. This is especially as a result of the insoluble nature of Nb and Ta, the Extraction of keratin from keratinous waste materials, such as chicken feathers, has been identified as the favourable approach in beneficiation of this biomass. The chemical extractions of keratin by reducing agents are usually preferred because the process is much faster than its counterpart, oxidation extraction.Valorisation of waste chicken feathers: Optimisation of
