Effect of seeding on product quality in batch antisolvent crystallization of Rare Earth Elements |
Qualifications2014 BEng (Hons) Chemical Engineering (NUST) 2018 PGDip in Project Management (PMZ) 2019 OSHEMAC (NSSA) Employment2014 – 2021 Effluent Plant Controller (Zambezi Tanners (Pvt) Ltd) Project DescriptionRare Earth Elements (REE) are valuable metals that have found use in many consumer end products such as hybrid cars, electronic devices, and magnets. Antisolvent crystallization is a novel technology for REE recovery from waste materials such as spent NiMH batteries and mine dumps. High supersaturation generated in antisolvent crystallization results in fine product crystals due to uncontrolled nucleation. These fines are difficult to handle in downstream separation processes such as filtration. The project aims to explore how seeding can be utilised in batch antisolvent crystallization to attain larger particle sizes with narrow PSD for easier handling. |
