Inorganic membrane percrystallisation in hydrometallurgy (2019–2022)
Inorganic membrane percrystallisation is a recent breakthrough promising improved productivity, energy savings and the ability to tailor particle properties. This project aims to establish the engineering relationships between membrane properties and percrystallisation operating conditions with production rates and product qualities. To do this, a mechanistic model will be developed encompassing solution transport phenomena, crystal nucleation-growth-agglomeration and engineering process parameters affecting single and binary salt systems. This model will provide a basis for technology development benefiting Australia, for example, it could significantly improve the production of nickel sulphate for the growing battery materials market.
