Abstract

A method (10) for the recovery of solid magnesium sulphate from a process solution (12) containing dissolved magnesium sulphate. The method comprises concentrating the process solution (12) using membrane filtration (16) to form a concentrated process solution, and treating the concentrated process solution to precipitate solid magnesium sulphate.
