Investigating the effect of mixing on crystal growth during antisolvent crystallization of REE from NiMH battery leach liquors |
Qualifications2013 BSc Chemical Engineering (University of Cape Town) Employment2019-2020 Process Engineer (Lydenburg Smelter, Crusher Fines Recovery Plant) 2016-2018 Director (Urban Ores Recycling) 2015-2016 Process Control Engineer (Mintek) 2014-2015 Engineer-in-training (Mintek) Project DescriptionRare earths elements (REEs) are major constituents used in manufacturing of high-end technology products we use in our everyday lives including electronic gadgets, computers, and memory storage devices. Efficient recovery technologies and sources of REEs are required to meet the future demand of these elements. Nickel metal hydride (NiMH) batteries used in hybrid electric vehicles contain large amounts of REEs and prone to limited life span. In this study, it was proposed to design an antisolvent crystallization process to recover REEs from NiMH batteries synthetic leach liquors using a confined impinging jet crystallizer. The study will primarily focus on the effect of mixing/hydrodynamics on the crystal size and crystal size distribution with neodymium sulphate as a model system. |
