The present application provides a process and system for recovery of rare earth elements. In particular, the present application provides a process for obtaining a precipitate of rare earth elements (REE), comprising : (a) obtaining an acidic composition comprising the REE (such as, for example, a pregnant leach solution); (b) adding a reducing agent to the acidic composition and adjusting the pH with a basic agent; (c) adding oxalate directly to the composition formed in step (b) and mixing to form an REE oxalate precipitate; (d) removing the REE oxalate precipitate from the mixture of step (c).
